The AMD Radeon RX 5500 XT Review, Feat. Sapphire Pulse: Navi For 1080pby Ryan Smith on December 12, 2019 9:00 AM EST
2019 has been a tremendous year for AMD on all fronts. Their CPU division has, of course, been flipping tables left and right across consumer, server, and workstation CPUs. Meanwhile the GPU division has spent their year wrapping up and shipping their Navi GPUs, the first parts utilizing their new RDNA architecture. Now, as the rest of 2019 quickly runs by, AMD’s GPU division is going to get in one final word with the launch of their new mainstream, 1080p-focused Radeon RX 5500 XT cards.
The launch of the 5500 XT has been sort of a weird path for AMD. The company first announced the overarching Radeon RX 5500 series back at the start of October. That announcement was OEM-centric, with AMD announcing the parts that their OEM partners would be shipping in desktops and laptops for the holiday season. Retail cards were part of AMD’s plans as well, of course, but those received a rather nebulous “Q4 2019” launch date. But now with less than two weeks to go until Christmas, the retail RX 5500 cards are here at last – and not a moment too soon.
Launching today are AMD’s Radeon RX 5500 XT cards. These cards are aimed at the sub-$200 market for 1080p gaming, effectively (and finally) replacing AMD’s long-lived Radeon RX 580 and RX 570 cards, and going head-to-head with NVIDIA GeForce GTX 1650 and GTX 1660 families. As is typical for AMD in this price range, the company is actually launching two different configurations of the RX 5500 XT: we’re getting both 8GB cards, as well as 4GB cards as a budget option. Both cards are clocked the same, but as we’re entering 2020, the ramifications of 4GB of VRAM versus 8GB are great enough that it creates some real differences between the cards. The 8GB RX 5500 XT will be taking up the all-important $199 slot, while the 4GB RX 5500 XT will hit the shelves starting at $169.
Underpinning the new cards is AMD’s new Navi 14 GPU. As has been the case with lower-end GPUs in past generations, AMD has taken the constituent parts of their Navi architecture and assembled a smaller, cheaper, and less power-hungry GPU that’s better suited for the sub-$200 market. In the process Navi 14 forgoes some CUs, some ROPs, and some memory bandwidth compared to the original Navi 10, but it retains all of the features of the underlying RDNA (1) architecture, including the efficiency improvements AMD has made there. And, for that matter, it gets the full-fat media processing block as well.
In terms of die size and transistor counts, AMD has dropped about 3.9B transistors from Navi 10, which comes to 38% fewer transistors overall. This translates into a die size of 158mm2, an almost perfectly matched 37% smaller than Navi 10. Compared to AMD’s previous generations of parts, comparisons are a bit rocky since performance targets and die sizes have gone up overall, but this works out to a transistor count about 12% higher than Polaris 10/20/30, in just 70% of the space. Polaris 11 (used in RX 460/560) might be a more apt comparison here, in which case AMD has increased their transistor count by 113% while only increasing the die size by 28%.
These improvements come thanks to TMSC’s 7nm process, of course. The heart of AMD’s entire next-generation product stack across CPUs and GPUs for 2019, AMD is once again using this process for their latest Navi GPU. This remains a critical edge for AMD on a competitive basis, as NVIDIA is still using TSMC 12nm – a 16nm-derrived process – for their GPUs. This gives AMD the ability to lay down smaller transistors operating at lower power levels, with the trade-off being that 7nm is a younger, more expensive process. And, if reports are to be believed, one that TSMC’s customers are jockeying to secure wafer starts due to very high demand.

Curiously and atypically for an upper-tier XT-type part, AMD is not using a fully-enabled Navi 14 GPU here. While AMD has never officially confirmed the complete specs of Navi 14, we know from other Navi 14 products – particularly, the Radeon Pro 5500M parts going into Apple’s laptops – that Navi 14 comes with 24 CUs. So a 22 CU part by contrast is an unexpected castration, though ultimately it doesn’t affect performance too much. AMD hasn’t specifically said why they’re not using all 24 CUs, but given how price sensitive this market is and how popular TSMC’s 7nm process has been, I would not be surprised if AMD is aiming to get as many useful dies as they can off of their Navi 14 wafers.
Navi 14 Block Diagram (Unofficial)
At any rate, the RX 5500 XT joins AMD’s family underneath the RX 5700, with 14 fewer CUs (-39%) than AMD’s next best card. However, while the CU counts are down, the clockspeeds will be up slightly, with the RX 5500 XT carrying a game clock of 1717MHz, 92MHz (6%) higher than the RX 5700. Similarly, the maximum boost clock is higher as well, to 1845MHz.
In terms of overall GPU performance then, at full clockspeeds the RX 5500 XT has a peak compute/shader throughput of 5.2 TFLOPs. This is 35% below the peak rate of the RX 5700, and is fairly typical for the kind of jump we see between card tiers.
Meanwhile on the memory side of matters, the RX 5500 XT gets a narrower memory bus as well. Coming off of the RX 5700 series and its 256-bit bus, AMD’s mainstream cards instead come with a 128-bit memory bus. However, that is the only change for memory; AMD will be using GDDR6 for these cards as well. So while the effective drop in memory bandwidth relative to the RX 5700 is significant – going from 448GB/sec to 224GB/sec – it will be the first time that GDDR6 has shown up in a sub-$200 AMD video card. As a result, the RX 5500 XT still has access to a good deal of memory bandwidth, and in this respect should punch above its weight compared to earlier 128-bit bus cards. As for total memory capacity, as previously mentioned AMD and its partners are shipping both 8GB and 4GB cards as performance and value options respectively.
Finally, AMD has set the total board power (TBP) for these cards at 130W. This is notably lower than their OEM counterparts, which ship with similar performance specifications, but a 150W TBP. The OEMs cards admittedly had us a bit worried there – 150W was uncomfortably high, and only a bit lower than the 180W TBP of the RX 5700 – so it’s good to see that AMD is being a bit more aggressive in curtailing power use for their retail cards, thereby boosting their power efficiency. Still, on paper the RX 5500 XT is set to deliver 65% of the RX 5700’s performance for 72% of its power budget, so we’ll have to see what the final power figures look like. And, for that matter, if 130W is enough for the 5500 XT to sustain its high clockspeeds, or if the cards will need to back off a bit to meet their power limits.
Product Positioning & The Competition
Within AMD’s product stack, the new Radeon RX 5500 XT cards are decidedly aimed at the 1080p market. Whereas the 5700 series cards were mostly aimed at 1440p – and delivered well in that respect – the RX 5500 XT doesn’t have the kind of performance to keep up there. Instead, the RX 5500 XT should be able to game at 1080p with few (if any) compromises, especially on the more spacious 8GB card.
Meanwhile, although AMD does have reference RX 5500 series cards, which is what they’ve been shipping to OEMs for the past couple of months, we won’t be seeing these cards in retail. Instead, today’s launch, which is very much a hard launch, is purely driven by the board partners, who are releasing their fully custom designs today. As these are sub-$200 cards we won’t be seeing anything too exotic – mostly the usual variations on two and three fan designs – though factory overclocked cards will be peppered into the mix.
And while this is a hard launch, I’m doubtful we’ll see the first batches of RX 5500 XT cards remain in stock for long. Looking at sales numbers and inventories for existing cards ahead of today’s launch, retailers have had trouble keeping much of anything in stock – video cards or other computer parts – so the RX 5500 XT isn’t likely to be much different. That means that if you want to be fragging people by Christmas morning, it may be prudent to pick up a card sooner than later – but only after you finish reading this review.
Within AMD’s product stack then, the release of the RX 5500 XT means that AMD is finally beginning the process of winding down the production and sales of the Radeon RX 590/580/570. With the new Navi-based cards outperforming AMD’s very long-lived Polaris cards all the while drawing less power, the only thing keeping the RX 5500 XT from immediately replacing the RX 500 series is going to be how well AMD and its board partners can keep the market stocked. In the meantime, expect to see retailers running close-out sales on the RX 500 series to get their remaining inventory sold.
Meanwhile, before we go any farther, some expectation management is in order here. While the RX 5500 XT replaces the RX 500 series within AMD’s immediate product stack, RX 5500 XT and Navi 14 are not meant to be upgrades for the RX 500 series. That is a job for the RX 5700 series. Instead, the RX 5500 XT is closer to an upgrade for the Radeon RX 560; Navi 14 is by and large the 7nm successor to Polaris 11. AMD has been selling the RX 580 and RX 570 cards for very cheap over the last 18 months, and while this has led to some great deals, it has admittedly distorted the market a bit. For the moment, at least, AMD isn’t looking to deliver substantially more performance at $160-$200 than they were before. Instead, it’s about delivering newer, more efficient technologies.
As for the competition, the new Radeon cards will be going head-to-head with NVIDIA’s GeForce GTX 1660 and GTX 1650 Super cards. All based on the same TU116 GPU, NVIDIA recently refreshed the lineup with the launch of their Super variants, which definitely felt like pre-emptive responses to the RX 5500 series. As a result of how the two companies are very narrowly and very specifically controlling their prices and product positioning, there’s not quite a 1:1 match between Radeon and GeForce parts right now. The 4GB RX 5500 XT is $10 more expensive than the GeForce GTX 1650 Super, and the 8GB RX 5500 XT is $10 cheaper than the GeForce GTX 1660. This also happens to pretty accurately reflect their relative performance: the 5500 XT can match wits with the 1650 Super, but it falls short of the 1660.
For AMD’s part, then, the company is further sweeting the deal with a game bundle. Along with the 3 month free trial to Microsoft’s Xbox Games Pass program that has been coming with virtually every other piece of AMD hardware for the last half a year, the company is also bundling the forthcoming “Master Edition” of Monster Hunter: Iceborne. This is the Iceborne expansion bundled with the base game, and is set to be released in 2020. Meanwhile NVIDIA isn’t running any kind of bundle for their GTX cards, so this is an area where AMD has an edge.
Though with most of Newegg’s video card stock being anything but in stock, the point may be a bit moot right now. With less than two weeks to go until Christmas, getting ahead of any good sub-$200 cards is likely to be a tricky proposition, especially with the GeForce GTX 1650 Super lineup entirely sold out.

Valantar - Thursday, December 12, 2019 - linkWhat? This class of GPU is in no way whatsoever capable of gaming at 4K. Why include a bunch of tests where the results are in the 5-20fps range? That isn't useful to anyone.
Zoomer - Saturday, December 21, 2019 - linkAT used to include. I just ignored it for a card of this class; probably others did as well.
Ravynmagi_ - Thursday, December 12, 2019 - linkI lean more Nvidia too and I didn't get that impression from the article. I felt it was fair to AMD and Nvidia in it's comparison of the performance and facts. I wasn't bothered by where they decided to cut off their chart.
FreckledTrout - Friday, December 13, 2019 - linkSame here. I don't need to see numbers elucidating how bad these low end cards are at 4k. Let's move on.
Dragonstongue - Thursday, December 12, 2019 - linkI <3 how compute these days adamantly refuse to use the "old standard"
this shows Radeon in vastly different light, as the different forms of such absolutely show difference generation on generation, more so Radeon than Ngreedia err I mean Nvidia.
seeing as one can take the wee bit of time to have a -pre set that really needs very little change (per brand and per specific GPU being used)
instead of using "canned" style bechmarks, that often are very much *bias* towards those who hold more market share and/or have the heavier fist to make sure they are shown as "best" even when the full story simply is NOT being fully told...yep am looking direct at INTC/NVDA ... business is business, they certainly walk that BS line constantly, to very damaging consequence for EVERYONE
I personally think in this regard, AMD likely would have been "best off" to up the power budget a wee touch, so the "clear choice" between going with older stuff they probably and likely not want to be producing as much anymore (likely costlier) that is RX 4/5xx generation such as the 570-580 more importantly 590, this "little card" would be that much better off, instead, they seem to "adamant" want to target the same limiting factor of limited memory bus size (even though fast VRAM) still wanting to be @ the "claimed golden number" of "sub" $200 price point --- means USA or this price often moves from "acceptable" to, why bother when get older far more potent stuff for either not much more or as of late, about the same (rarely less, though it does happen)
1080p, I can see this, myself still using a Radeon 7870 on a 144Hz monitor "~3/4" jacked up settings (granted it is not running at full rate as the GPU does not support run this at full speed, but my Ryzen 3600 helps huge.
still, a wee bit more power budget or something would effectively "bury" or make moot 580 - 590, then wanting to sell for that "golden" $200 price point, would make much more sense, seeing as they launched the 480 - 580 "at same pricing" (for USA) in my mind, and all I have read, with the terrific yields TSMC has managed to get as well as the "reasonable low cost to produce due to very very few "errors" THIS should have targeted 175 200 max.
They are a business, no doubt, though they in all honesty should have looked at the "logical side" that is, "we know we cannot take down the 1660 super / Ti the way we would like to, while sticking with the shader count / memory bus, so why not say fudge it, add that extra 10w (effectively matching 7870 from many many generations back in the real world usage) so we at least give potential buyers a real hard time to decide between an old GPU (570-580-590) or a brand spanking new one that is very cool running AND not at all same power use, I am sure it will sell like hotcakes, provided we do what we can to make sure buyers everywhere can get this "for the most part" at a guaranteed $200 or less price point, will that not tick our competition right off?"
thesavvymage - Thursday, December 12, 2019 - linkWhat are you even trying to say here.....
Valantar - Thursday, December 12, 2019 - linkI was lost after the first sentence. If it can be called a sentence. I truly have no idea what this rant is about.
Fataliity - Thursday, December 12, 2019 - linkI think the game bundle is what they chose as their selling point. I'm sure they get a good deal with game pass being the supplier of CPU/GPU on xbox. So their bundle is most likely almost free for them. Which pushes the value up. Without bundle I imagine 5500 4gb being 130 and 8gb being 180.
TheinsanegamerN - Sunday, December 15, 2019 - linkThat's a LOTTA words just to say "AMD just made another 580 for $20 less, please clap."
kpb321 - Thursday, December 12, 2019 - linkThe ~$100ish 570's still look like a great deal as long as they are still available. For raw numbers they have basically the same memory bandwidth and compute as a 5500 but the newer card ends up being slightly faster and uses a bit less power. It is overall more efficient but IMO no where near enough to justify the price premium over the older cards. I'm not as sure that the 570/580 or 5500 will have enough compute power for the 4 vs 8gb of memory to really make a difference but my 570 happens to be an 8gb card anyway.
