Intel is set to roll out its Xeon W-2400 and Xeon W-3400-series processors for high-end desktops (HEDTs) and extreme workstations on February 15, and as their launch date looms, the first benchmark results have begun to leak. As it usually happens, this time around Intel's upcoming HEDT flagship — the56-core Xeon W3495X— landed in the Geekbench 5 database(via@Benchleaks), which is proof that the CPU is in the wild already.
Intel's return to HEDT and extreme workstation space is important by itself. In recent years, AMD essentially ousted Intel from these markets with its Ryzen Threadripper processors. However, Intel's Sapphire Rapids design enables Intel to re-enter the game with high core counts, decent clocks, and support for up to 4TB of DDR5 memory. In addition, it appears that Intel will offer multiple X-series models with an unlocked multiplier for those that want to overclock their machines.
Intel's flagship Xeon W3495X CPU packs 56 high-performance Golden Cove cores and a massive 105MB L3 cache. It runs at a default clock of 1.90 GHz and can accelerate to 4.80 GHz when possible, so expect it to offer quite decent performance. Meanwhile, the sample listed in the Geekbench 5 database ran at around 3.20 GHz (which is too low). It allegedly also used a quad-channel memory subsystem, so we shouldn't come to any serious conclusions about the CPUs' performance.

Platform-wise, Intel's new W790 provides PCIe Gen5 (by CPU),16 PCle 4.0 lanes, up to 12 PCle 3.0 lanes, up eight SATA ports, up to five USB 3.2 Gen2x2 connections, up to 10 USB 3.2 Gen2 ports,Wi-Fi 6E capabilities,and supportstwo 2.5GbE PHY controllers.
Obviously, all reliability, availability, and serviceability capabilities of modern Intel Xeon processors are also supported, just like things like virtual RAID on CPU (VROC), and remote management. Of course, HEDTs and workstations would certainly benefit from Thunderbolt 4 and Wi-Fi 7, so we would expect workstation makers to install the appropriate controllers themselves.
In any case, for now, it appears that Intel is about to re-enter HEDT and extreme workstation markets, giving AMD's Ryzen Threadripper Pro 5000WX-series CPUs a strong rival for the first time in years.

dalek1234 Your table with Geekbench result has misaligned headers. It make it look like AMD lost in almost every benchmark, when it fact those poor results belong to Intel.
Which bring me to the next point: " a strong rival ". What are you smoking? Intel is behind AMD in 7 out of 8 of your benchmarks, sometimes by a big margin. And the only benchmark AMD loses to is "crypto". Nobody does crypto on a CPU, so that's a useless benchmark anyway. And what about power consumption and heat generated? I bet that even with the poor Xeon performance, it probably sucks rediculous amounts of power compared to Threadripper.

I agree with most of your points, except crypto refers to cryptographic functions which can be a significant piece of the workload for the target market. It does not refer to crypto currency.
Considering the low single core crypto score, it seems a strange outlier for unusually high multi core score.

You're right about single and mult core crypto scores. They don't make sense.

PCWarrior This is not a 56core cpu. It is a 28core/56thread cpu. What is reported in Geekbench is the number of logical cores.
https://browser.geekbench.com/v5/cpu/20093542
This is evidenced by the L1 and L2 Cache numbers where the multiplier is 28 and not 56.
L1 Instruction Cache 32.0 KB x 28
L1 Data Cache 48.0 KB x 28
L2 Cache 2.00 MB x 28Intel will be entering the HEDT market again with prices up to $2000 or even up to $3000 but not higher. So they won't be offering their 56-core server parts as workstation offerings. It is very likely that the HEDT flagship will be markeked as the successor of the 28core W3175X which launched for $3000. In a market where even consumer-grade higher-end boards cost over $600, good motherboards for the HEDT platform will easily cost $1000-$2000, making a $2000-$3000 cpu kind of a reasonable pairing.

And yet the spec of the Xeon W9-3495X, as entered in the chart, is 56 cores/112 threadsReply
bit_user As in some other articles I've seen, the table column headings are shifted left by one.

I think adding a column heading at the left would fix it (maybe call it "Test").

What are you smoking?I generally agree, but there's a possibility this is still just an engineering sample, which typically perform a worse than final production examples. I'm rather suspicious that's what we're seeing, since especially the single-core scores don't tally with what we saw when Alder Lake launched against Ryzen 5000.
Regarding multi-threaded, 56 Golden Cove cores should be very competitive against 64 Zen3 cores. It's really the matchup against the 7000-series Threadripper that will be interesting.

https://browser.geekbench.com/v5/cpu/20093542If the model number is being correctly reported and they're not doing anything weird by restricting cores or running without hyperthreading, then it's truly a 56-core/112-thread CPU.

Next, let's look at scaling data, to see how that aligns with different hypothetical core & thread counts. Below, I've taken each CPU's multithreaded score and divided it by the respective single-threaded score. What we get tells us how well performance scaled up.

This shows is that Geekbench's multithreaded tests apparently don't scale very well, because even the 64-core/128-thread TR 5995WX tends to scale up to about 30x the performance of single-threaded. There could be lots of reasons for this, including poorly-written benchmarks or perhaps encountering memory bottlenecks or excessive contention for L3 cache. Also, the single-core tests will be running at max turbo, while multithreaded tests will tend to run at much lower base clocks.

Check the source link above, and you'll also find a list of the 2400-series models. I expect the 2400-series CPUs to range from about $800 to $3500, and the 3400-series CPUs to range from about $2k to $7k.

The 3495X is indeed a 56core/112thread cpu but apparently in this reported benchmark it run with half part of it disabled. Not only is this evident by the reported cache multipliers (x28 instead of x 56) but also by the fact that the reported memory channels are 4 instead of 8 (all the leaked slides are mentioning 8 memory channels). After all the 3495X is a two-tile cpu so maybe it was running with one tile disabled?

Again, this silicon is quite likely an engineering sample and Geekbench could've had some bugs in the code trying to query its stats. Two potential sources of mis-reporting I find more plausible than that it was really running on just 28 cores. Anyway, we'll know soon enough how the 3495X truly performs.
