Ice Lake Xeon Processor List
Intel is introducing around 40 new processors across the Xeon Platinum (8300 series), Xeon Gold (6300 and 5300 series) and Xeon Silver (4300 series). Xeon Bronze no longer exists with Ice Lake. Much like the previous generation, the 8/6/5/4 segmentation signifies the series, and the 3 indicates the generation. Beyond that the two digits are somewhat meaningless as before.
That being said, there is a significant change. In the past, Platinum/Gold/Silver also indicated socket support, with Platinum supporting up to 8P configurations. This time around, as Ice Lake does not support 8P, all the processors will support only up to 2P, with a few select models being uniprocessor only. This makes the Platinum/Gold/Silver segmentation arbitrary, if only to indicate what sort of performance/price bracket the processors are in.
On top of this, Intel is adding in more suffixes to the equation. If you work with Xeon Scalable processors day in and day out, there is now a need to differentiate the Q processor from a P processor, and an S processor from an M processor. There’s a handy list down below.
SKU List
The easiest way with this is to jump into the deep end with the processor list. RCP stands for recommended customer price, and SGX GB stands for how large Software Guard Extension enclaves can be – either 8 GB, 64 GB, or 512 GB. Cells highlighted in green show highlights in the stack.

The peak turbo on these processors is 3.7 GHz, which is much lower than what we saw with the previous generation. Despite this, Intel seems to be keeping prices reasonable, and enabling Optane support through most of the stack except for the Silver processors (which has its own single exception).
New suffixes include Q, for a liquid cooled processor model with higher all-core frequencies at 270 W, and Intel said this part came about based on customer demand. The T processors are extended life / extended thermal support, which usually means -40ºC to 125ºC support – useful when working at the poles or in other extreme conditions. M/N/P/V specialized processors, according to our chat with Lisa Spelman, GM of the Xeon and Memory Group, are the focal points for software stack optimizations. Users that want focused hardware that can get 2-10%+ more performance on their specific workload can get these processors for which the software will be specifically tuned. Lisa stated that while all processors will receive uplifts, the segmented parts are the ones those uplifts will be targeted for. This means managing turbo vs use case and adapting code for that, which can only really be optimized for a known turbo profile.
Competition
It’s hard not to notice that the server market over the last couple of years has become more competitive. Not only is Intel competing with its own high market share, but x86 alternatives from AMD have scored big wins when it comes to per-core performance, and Arm implementations such as the Ampere Altra can enable unprecedented density at competitive performance as well. Here’s how they all stand, looking at top-of-stack offerings.

At 40 cores, Intel does look a little behind, especially as Ampere is currently at 80 cores and a higher frequency, and will come out with a 128-core Altra Max version here very shortly. This means Ampere will be able to enable more cores in a single socket than Intel can in two sockets. Intel’s competitive advantage however will be the large current install base and decades of optimization, as well as new security features and its total offering to the market.
On a pure x86 level, AMD launched Milan only a few weeks ago, with its new Zen 3 core which has been highly impressive. Using a chiplet based approach, AMD has over 1000 mm2 of silicon to spread across 64 high performance cores and massive amounts of IO. Compared to Intel, which is around 660 mm2 and monolithic, AMD has the chipset onboard in its IO die, whereas Intel keeps it external which saves a good amount of idle power. Top of stack pricing between AMD and Intel is similar now, however AMD is also focusing in the mid-range with products like the 7F53 which really impressed us. We’ll see what Intel can respond with.
In our numbers today, we’ll be comparing Intel’s top-of-stack to everyone else. The battle royale of behemoths.
Gen on Gen Improvements: ISO Power
It is also important to look at what Intel is offering generationally in a like-for-like comparison. Intel’s 28-core 205 W point for the previous generation Cascade Lake is a good stake in the ground, and the Intel Xeon Gold 6258R is the dual socket equivalent of the Platinum 8280. We reviewed the two and they performed identically.
For this review, we’ve put the 40-core Xeon Platinum 8380 down to 205 W to see the effect of performance. But perhaps more in line, we also have the Xeon Gold 6330 which is a direct 28-core and 205 W replacement.

So the 6330 might seem like a natural fit, however, the 8352Y feels better given that it is more equivalent in price and offers more performance. Intel is promoting a +20% raw performance boost with the new generation, which is important here, because the 8352Y still loses 500 MHz to the previous generation in all-core frequency. The 8352Y and 6330 do make it up in the extra features, such as DDR4 channels, memory support, PCIe 4.0, Optane support, SGX enclave support, and faster UPI links.
This review has a few of our 6330 numbers that we’ve been able to run in the short time we’ve had the system.

that's a lot of upgrade for intelGomez Addams - Tuesday, April 6, 2021 - link
That is a curious-looking wafer. I thought it was fake at first but then I noticed the alignment notch. Actually, I'm still not convinced it's real because I have seen lots and lots of wafers in various stages of production and I have never seen one where partial chips go all the way out to the edges. It's a waste of time to deal with those in the steppers so no one does that.JCB994 - Tuesday, April 6, 2021 - link
Periphery defects? I used to deal with those...buildup of material that would breakdown during wet processing and stream particles all over the wafer. Running partials as far out as possible helped. Nowadays...do they still use big wet benches? I have been out awhile...Gomez Addams - Tuesday, April 6, 2021 - link
Yes, they do. That's one of the systems I spent lots of time working on. Those don't look defects to me. They are just a continuation of the chip pattern.FullmetalTitan - Saturday, April 24, 2021 - link
Still the most chemical efficient tools for some etch processes. It is odd to see die prints out to the edge all around, usually at least the 'corners' are inked out/not patterned by the time it hits copper layers because printing features out that far can increase the chances of film delamination, which just leads to more defectivity. I suppose on DUV tools the extra few seconds to run those shots isn't THAT bad on non-immersion layers, but it adds up over timeArsenica - Tuesday, April 6, 2021 - link
It isn´t real if it doesn´t have DrIan bite marks./jk

@Gomez AddamsI spent my entire career working in the semiconductor industry, although in IT, and I have seen many wafers from 4" to 12" and printing partial die off the edge of the wafer is quite common.

So when are we going to hit 450 mm / 18" waffers?Are we ever going to get Hexagonal Die's to maximize possible Yields?
http://www.semiconductor-today.com/news_items/2020...
https://semiaccurate.com/2015/05/18/disco-makes-he...
They can already do that for simple LED's, but trying to bring Hexagonal IC Dies into existence is going to be exciting because there is a theoretical 62.5% increase in Manufactured Dies for a given Waffer Diameter and using Hexagonal IC Dies of a similar/identical area.

@Kamen Rider Blade - "So when are we going to hit 450 mm / 18" waffers?"It seems the desire to move to EUV distracted TSMC, Samsung and Intel who are probably the only companies that were really interested in 450mm.
saratoga4 - Tuesday, April 6, 2021 - link
>So when are we going to hit 450 mm / 18" waffers?For logic, never since there is little to no advantage to larger wafers. Possibly NAND might use it, but we'll see if its even worth it there.
>Are we ever going to get Hexagonal Die's to maximize possible Yields?
Probably not for logic. With reticle sizes getting smaller in the coming nodes, it makes even less sense going forward then it did in the past, and it didn't make much sense then to begin with.
