Intel’s new Cascade Lake-X high-end desktop lineup got here out this week, and on this case, the efficiency information is available in second to the worth. It prices you nearly precisely half as a lot to purchase any given Cascade Lake-X CPU as it will have price for its Skylake-X counterpart final 12 months, in apparent response to AMD’s Threadripper CPUs—and certain partly to the Ryzen 9 3950X, due out in November together with the subsequent era of Threadrippers.
Skylake-X vs Threadripper 2x
We do not have a agency set of specs on the third-generation Threadrippers but, however we are able to get a fast take a look at how Cascade-X compares with Threadripper 2000 beneath:
Intel CPU Mannequin
AMD CPU Mannequin
For one instance, this 12 months’s high-end i9-10980XE goes for $980—and final 12 months’s 9980XE went for just below $2,000. We see roughly the identical price discount throughout the board, all the way down to the 10900X at $590 vs final 12 months’s 9900X at $990. This takes purpose squarely at Threadripper. The fascinating query is how AMD will reply with new Threadripper pricing subsequent month; we already know the corporate at the least pretends to get pleasure from taking part in elaborate worth video games.
PCIe four.zero lanes
Cascade Lake-X CPUs include 48 PCIe lanes, up from 4 Skylake-X. Nevertheless it’s nonetheless 16 shy of Threadripper 2990WX’s 60 lanes. We nonetheless do not know what number of PCIe lanes Threadripper 3000 CPUs will get pleasure from, however we really feel protected saying it needs to be at the least as many because the 2990WX. If this era’s Threadripper follows the final, TR3 needs to be primarily a cut-down Epyc Rome lineup, which ought to both imply 60 lanes once more (if it maintains socket compatibility) or 120+ lanes (if it requires a brand new socket design).
Marketed as “Turbo Enhance Max three.zero,” Intel has modified its frequency administration to help improved turbo frequencies for each the quickest and next-fastest pair of cores. Flippantly-threaded workloads will goal these 4 quickest cores; a brand new Home windows scheduler patch intelligently rotates workloads throughout favored cores to work with this scheme instantly, enhancing efficiency and reliability. The brand new Home windows scheduler arrives with the Home windows 10 2H19 replace.

Reminiscence help has doubled and clock pace has improved since Skylake-X, up from 128GB DDR4-266 to 256GB DDR4-2933. Intel has additionally added new onboard Wi-Fi 6 and a pair of.5G Ethernet help.
Deep Studying Enhance—a small extension to the x86-64 instruction set, which affords vital advantages for sure AI-driven workloads—is obtainable in Cascade Lake-X. Though purposes should be constructed with compilers that acknowledge the brand new DLB directions, throughput for these workloads, which may embrace picture tagging and enhancement, video evaluation, and voice recognition can simply double with their availability.
Intel Efficiency Maximizer
IPM, which debuted as an overclocking software for ninth-generation Okay-series processors, additionally helps Cascade Lake-X. IPM is Intel’s reply to AMD’s comparable Precision Enhance Overdrive. It additionally permits lovers to extra simply obtain, monitor, and preserve the utmost clock price their particular person CPU (and cooling system) can help.
