Hands on with the 56-core Xeon Platinum 9200 CPU: Intel’s Biggest CPU Package Everby Ian Cutress on April 8, 2019 11:00 AM EST
When Intel announced the new Cascade Lake family as officially launched last week, it added a new product segment to its portfolio – the ‘Advanced Performance’ or AP. These come in the form of the Xeon Platinum 9200 family, and feature two of Intel’s high-end processors within a single package, offering double the cores and double the memory in a much denser environment. These processors are focusing purely on density, and are BGA only so they will only be sold as complete systems by OEMs, who actually buy them from Intel and make modifications. We had the opportunity to hold one of these big CPUs and take some pictures.
The package measures 76.0 x 72.5 mm, making it Intel’s largest CPU based* package ever, beating out the old Intel Pentium Pro, which was 67.6 x 62.5 mm, and AMD’s EPYC package, which is 75.4 x 58.5 mm.
Inside the package is two XCC enabled silicon die, one designated a master, and one a slave. The die themselves are ~694mm2 each.
The Biggest Baller In The Park
The socket is officially called FCBGA5903, which stands for flip-chip ball-grid array 5903, with 5903 being the number of contacts or ‘balls’ on the underside which goes onto the motherboard, much like an embedded chip. By contrast, AMD’s EPYC chip has 4094 pins. The reason for all these contacts are mostly in the memory: as this Platinum 9200 processor has twelve memory channels, these all require pins. There are also some more for power, as the TDP for the 56-core version is 400W.
To begin, Intel is offering four different types of Platinum 9200:
|Intel Xeon Platinum 9200 Family
(Cascade Lake AP)
|Platinum 9282||56 C / 112 T||2.6 GHz||3.8 GHz||77.0 MB||400 W||head|
|Platinum 9242||48 C / 96 T||2.3 GHz||3.8 GHz||71.5 MB||350 W||shoulders|
|Platinum 9222||32 C / 64 T||2.3 GHz||3.7 GHz||71.5 MB||250 W||knees|
|Platinum 9221||32 C / 64 T||2.1 GHz||3.7 GHz||71.5 MB||250 W||toes|
In terms of weight, the processor is definitely around 200-300g, or half a pound. This was measured very scientifically by comparing it in my hands to the weight of my heaviest phone, and then comparing it to two phones. The chip certainly has some hefty bulk, but given that it is a BGA design, it’s unlikely that even people using the chip will ever hold it.
If we look side on to the design, we can see that the package actually has three distinct layering stages (five, if you include the caps). The light brown and dark brown layering totals up to 18 layers (recorded by eye, hard to see in difficult light), and the dark brown layers are clearly double the thickness of the light brown layers, which might indicate that these are the power planes of the package. Normally we see processors with anywhere from 8-12 layers total, so this is another step up above that.
A close up of the ball array shows the fine pitch between the contacts. The capacitors on the underside are extremely tiny in comparison to other CPUs - I mean really small. Each of these corners has 87 capacitors, making for a total of 348.
Pricing for this family of processors is not expected to be disclosed. Intel has stated that as they are selling these chips as part of barebones servers to OEMs that they will unlikely partition out the list pricing of the parts, and expect OEMs to cost them appropriately. Given that the new high-end Intel Xeon Platinum 8280L, with 28 cores and support for 4.5 TB of memory, runs just shy of ~$18k, we might see the top Xeon Platinum 9282 be anywhere from $25k to $50k, based on Intel margins, OEM margins, and markup.
*Intel may have FPGA products that exceed this size, mainly due to HBM and other chiplets on board.

GreenReaper - Monday, April 8, 2019 - linkWell, they both use a lot of power. Intel does go a little higher with speeds, which costs a little more.
10x is pushing it, but 2-2.5x, yeah. For some people that's not a consideration, but if it is then you can make a significant saving with AMD.
Ian Cutress - Monday, April 8, 2019 - linkThis is more a Xeon Phi replacement than an EPYC competitor.
HStewart - Monday, April 8, 2019 - linkI don't think Intel is too worry about EPYC - they have 4 and 8 cpu solution to deal with high core count.
Alexvrb - Monday, April 8, 2019 - linkWow I didn't know they started giving away free CPUs. I thought you had to pay for each one!
psychobriggsy - Wednesday, April 10, 2019 - linkAMD would be insane to price it that low, in light of Intel's pricing madness.
Ironic that Intel goes for quad-socket 28 core CPUs to dual-socket 56 core CPUs, whilst AMD goes from 32-core dual-socket CPUs to 64-core quad-socket CPUs.
Anyone requiring massive compute and memory bandwidth will be getting a dual or quad AMD 64-core system late this year if they have any influence over their in-house IT department buying habits.
phoenix_rizzen - Wednesday, April 10, 2019 - linkWhere have you seen mention of a quad-socket EPYC motherboard? Far as I've seen, AMD has stated they won't be supporting anything beyond dual-socket.
FATCamaro - Monday, April 8, 2019 - linkNice package...
CityBlue - Monday, April 8, 2019 - linkI know Intel needed something to compete (on paper) with AMD, but this SKU is a total joke, and will sell in tiny numbers. I'm really not sure why Anandtech are giving this so much coverage, to be honest - is it for the LOLs?
Lord of the Bored - Monday, April 8, 2019 - linkPerhaps so Intel doesn't blacklist them.
bobhumplick - Monday, April 8, 2019 - linknow somebody get Derbauer one so he can delid it quick.
