Immediately, Intel is pulling the wraps off its latest lineup of Xeon processors sure for skilled workstations. The corporate is saying two product strains dubbed Xeon W-3400 and W-2400. The 3400 sequence are for “specialists” and carry a TDP of 350W. The 2400 CPUs are labeled “mainstream” and have a 225W TDP. One new “function” is Intel is segregating them into lessons because it does for its client CPUs. The 3400 sequence contains W9, W7, and W5 variants. The 2400 class will get W7, W5, and W3 SKUs. These CPUs will bridge the hole between its client and the information heart variations of Sapphire Rapids. Nonetheless, they don’t seem to be HEDT CPUs like Intel used to supply with the Core X lineup of yore.

The W-3400 and 2400 sequence share sure applied sciences however differ in all places else. Each households provide Intel TurboBoost Max 3.0 and Intel SmartCache (as much as 105MB). All of them assist AVX-512 and provide Superior Matrix Extensions (AMX). Past that, the specs are radically totally different. Because the flagship sequence, the 3400 line affords as much as 56 CPU cores. As much as 4TB of 4800MT/s DDR5 reminiscence with ECC is supported throughout as much as eight reminiscence channels. There are additionally as much as 112 PCIe 5.0 lanes and assist for Wi-Fi 6e as effectively. The W9 chip has 56 cores, the W7 affords 28, and the W5 has 16.

This household contains seven CPUs: two W9, three W7, and two W5. Pricing ranges from $1,189 for the 12-core, 24-thread base CPU to $5,889 for the flagship 56-core W9-3495X. TDPs vary from 350W to 270W, so these CPUs require substantial cooling.

The W-2400 sequence is a little more modest throughout the spec sheet. These CPUs provide 64 PCIe 5.0 lanes to the CPU in contrast with the 3400’s 112 lanes. They assist the identical 4800MT/s DDR5 reminiscence as their siblings however solely permit as much as 2TB as a substitute of 4TB. The reminiscence channels have been decreased from eight to 4 as effectively. The highest-tier W7 CPU affords 24 unlocked cores, with the W5 chip sporting as much as 16 cores. The baseline W3 model options an eight-core design. This lineup contains eight CPUs: two W7, and three for each W5 and W3. Pricing begins at simply $359 for the six-core, 12-thread CPU and goes as much as $2,189 for the 24-core, 48-thread mannequin.

So far as efficiency goes, Intel says its flagship 56-core processor is leaps forward of its predecessor. The corporate claims it’s as much as 28% quicker in single-threaded workloads and 120% in multi-threaded duties. These numbers are from a comparability between the 56-core Sapphire Rapids CPU and the 28-core Cascade Lake W-3275. Naturally, the efficiency delta depends upon varied components, together with the appliance used. Additionally, a handful of the CPUs in each households provide unlocked multipliers, however not all of them.

This slide reveals which SKUs are unlocked for each CPU households.

These CPUs are decidedly totally different from the corporate’s 4th Gen Sapphire Rapids Xeon Scalable CPUs for knowledge facilities and servers. All of them function decreased core counts and lack the pay-as-you-go accelerator choices. They’re anticipated to battle AMD’s upcoming Zen 4 Threadripper CPUs, that are but to be introduced. It’s rumored AMD will even be launching two product strains much like what Intel is doing. One might be much like a HEDT setup, like Intel’s 2400 sequence, and the opposite might be workstation-grade, just like the 3400 sequence. Rumors counsel AMD may go as excessive as 96-cores and 192-threads, the identical as its Epyc Genoa line.

These new Sapphire Rapids Xeon CPUs might be obtainable from Intel’s companions beginning immediately. You possibly can pre-order one now, and system availability begins in March. Observe that Intel’s pricing is simply “instructed,” so it might differ relying on which companion is promoting it.
