I look at this as Zen 5 test bed. Microsoft already said scheduler tweaks will come in Win 11 to better accommodate Zen 4 X3D, and I assume Linux kernel devs have been prepping for a bit.
I agree that Intel is already having to play with optimizing BIG.little with Alder Lake and Raptor Lake. Functionally this is kind of the same for AMD, where you want that cache hungry application all on the same core complex. Not exactly apples to apples, but it's at least still fruit.
This is a good opportunity to get a year or more of battle testing this stuff in the field to ensure its at least up to snuff, as well as plan future iterative improvements.
- dinvlad 4y agoI imagine Linus himself wanting the 7950X3D, given how he raved about 5950X earlier.
- MrFoof 4y agoHaving a 5950X myself I am very impressed at its power efficiency. I've tweaked mine a fair bit (plus aggressive memory with manually adjusted timings) and it's been great. Up to 6-cores it can sit at 5GHz all day long (on air!), and for full core workloads with the aggressive memory it's basically on par with a stock CPU if it was 18.5 cores, and is silent in all but the goofiest long-running workloads. I'd kill for more PCIe lanes, but for a budget data processing workstation (40Gbps networking, GPU as a budget DPU), it's been great. I believe the 7950X3D will have its voltage locked, but in terms of perf/W should still improve over the 5950X. And the 5950X's power efficiency is fantastic. The Ryzen Pro processors are also fantastic. The 5750GE was a decent clocked 8-core that peaked out of the box at only around 39W, supports ECC and DASH, other nice features like Memory Guard, Shadow Stack, etc. Those are great in 1L form factors where you can build capable physical clusters where nodes can idle at only 9W total power draw.
- dinvlad 4y agoYeah, impressive all around!
