Intel Announces 12th Gen Alder Lake-S CPUs: Specs and Benchmarks; Up to 30% Faster than Ryzen 5 5950X in Gaming


After a lot teasing and much more rumors/leaks, Intel at present introduced its twelfth Gen Alder Lake-S desktop processors. Described because the chipmaker’s largest design shift over the last decade, these CPUs function a hybrid core structure. On the top-end, we’ve acquired the 16 core i9-12900K with eight efficiency “Golden Cove” cores and eight effectivity “Gracemont” cores. The funds/midrange SKU is the Core i5-12600K with 10 cores, six efficiency, and 4 effectivity cores.

The L2 cache has been elevated throughout the board: 1.25MB for the efficiency cores and 2MB for the effectivity cores. The L3 cache is shared between all of the cores, being a relatively appreciable 30MB for the Core i9-12900K to 20MB on the 12600K.

Intel is promising an general IPC acquire of 19% in comparison with Cypress Cove (for Golden Cove) which powered the eleventh Gen Rocket Lake-S processors. What’s fascinating is the extensive efficiency delta throughout workloads. Whereas some functions present an IPC acquire of as much as 40%, a couple of present a regression of 10-15%. I reckon this has to do with the reminiscence latency and/or effectivity cores.

In gaming workloads, Intel claims a efficiency acquire of as much as 40% (in League of Legends DX11) and a mean enhance of 20% in comparison with the Core i9-11900K (vs Core i9-12900K).

In comparison with the Ryzen (ing) competitors, the Core i9-12900K is as much as 30% quicker than the Ryzen 5000 flagship, and 15% on common. As soon as once more, the efficiency varies tremendously from software to software. Whereas Shadow of the Tomb Raider sees a deficit of three% in comparison with the 5950X, the 12900K is on par with it in Crysis: Remastered. Then again, Troy: Complete Warfare sees the 12900K acquire a commanding 30% lead over the 5950X.

Unusually, Intel didn’t share any content material creation benchmarks evaluating its next-gen processors with the Ryzen competitors. Compared to Rocket Lake although, we’re taking a look at a wholesome acquire of as a lot as 100%, and 30-35% on common.

Artificial benchmarks like SYSmark and CrossMark present an uplift of 15-19% with the Core i9-12900K in comparison with the 11900K.

By way of I/O, we’re taking a look at 16 PCIe Gen 5.0 lanes from the CPU and 12 PCIe Gen 4 (or 16 Gen 3) lanes from the Z690 chipset. The DMI has additionally been doubled to extend the CPU to chipset bandwidth. WiFi 6E is supported and the platform options further USB 3.2 Gen 2 20Gbps slots.

Alder Lake-S helps each DDR5 and DDR4. The previous as much as 4800MT/s and the latter as much as 3200MT/s. Overclocking can, nevertheless, a lot increased frequencies.

Overclocking appears to be a serious focus with the Alder Lake-S desktop processors. The IHS (Built-in Warmth Spreader) is far thicker than previous generations, with the die/STIM being thinner.

The Intel Excessive Tuning Utility has gotten some good upgrades. It now helps ratio management for the effectivity/Gracemont cores, DDR5 assist, in addition to XTU Benchmark 2.0 integration on HWBOT.

Like many third-party apps, there’s additionally the choice to auto-overclock the CPU. In the intervening time, it’s solely out there on the Core i9-12900K and the Core i7-12700K, with the choice to overclock each the E and P core frequency, voltage, and so forth.

XMP 3.0 brings some enhancements to reminiscence overclocking as effectively. The overall variety of XMP profiles has been elevated to five (from 2), three from the seller, and two rewritable. Along with UI enhancements, the on-DIMM voltage can now be adjusted utilizing the PMIC.

Lastly, XMP 3.0 additionally adopts a dynamic frequency profile (very like CPU/GPU turbo enhance). Because of this the reminiscence runs at inventory JEDEC specs when idle, switching to the XMP enhance frequencies when beneath load.

Intel’s Alder Lake-S (Okay sequence) processors are slated to reach in retail shops globally across the 4th of November. It’s unclear whether or not the shares shall be sufficient to satisfy demand, however contemplating that the chipmaker doesn’t depend on any exterior foundry for the majority of its manufacturing, it must be optimistic.
