Overclockable Xeon Sapphire Rapids-WS for gaming benchmarks?

[toasty99]

Does anyone have any of the Sapphire Rapids WS CPUs that are overclockable? Or know of a publication that published gaming benchmarks?

 

I know it's highly impractical, but I'd be curious what the gaming performance on them is. The monolithic die models support ddr5 quad channel and have less cache. The multi-chip-module models support ddr5 8 channel ram and have more cache.

 

I'd be REALLY curious to see in spite of the impracticality of it which of these chips is faster and if they can beat out consumer CPUs in gaming. I'd suspect they can beat even a 7800x3d in gaming once overclocked (low stock clocks because workstation CPUs), but I've yet to see any tests and I don't have a grand to drop on something that's interesting rather than practical.

 

It would also be exciting to see someone try to get ddr5 stable at 4 and 8 channels and high speeds in my opinion, even though again it's not practical today.

 

This may be practical in 5 or so years though, kind of like X99 Xeon's were for a while.

I had considered this too, and would be interested if anyone had tested it. I didn't look when it came out, don't know if there might be some out there yet.

 

In theory, the cores are much the same as the P cores in Alder/Raptor Lake. I think the process is closer to Alder Lake so it might not clock as high, power aside. The extra ram channels may not help with gaming. Given that I wouldn't expect it to fighting at the top end of gaming CPUs even overclocked, but it would be a solid all round CPU if you want to do heavy workloads as well as game on the side. One reason I'm stuck on X299, nothing consumer tier is better yet.

Yup... x299 is where I'm going, rather than z790

I'm making the move from a Broadwell-E i7 6850K to Cascade Lake-X i9 10920x system. Waiting on parts to arrive though. Build is a month away.

The x99 chipset still has legs though for an older system. Just it's dated....

Little advice:

 

The i7 6850k is slightly overpriced on the used market. You can get $40 for it on eBay. 

 

The Xeon 1660v3 is an overclocking unlocked (v4 is locked though) 8 core Haswell processor just like the 5960x. It's less known though and there is a better bin 1680v3, so you can pick up the 1660v3 for $23 shipped on eBay.

 

If you'd like to upgrade your current system while you wait (or repurpose it later), with selling your 6850k you'd come out ahead. You lose a bit of IPC with the Haswell but it's very minor.

 

My experience with the 1660v3 is that the chips go somewhere around 4.4-4.6ghz when overclocked and cooled properly.

I have no plans to do what you suggest. The Intel Core i7 6850k is in use right now in my workstation. When I transition to the x299 platform, I will likely upgrade the living room media PC with the x99 platform... it's running an i5 Ivy Bridge/ ASUS z77 Sabertooth TUF board still.

I'm happy with my Broadwell-E for the 3 weeks till the Cascade Lake-X CPU gets here. My current RAM (listed in Sig) is QVL board compatible with the ASUS ROG Strix x299-E Gaming II motherboard on order. The mobo is due at the end of the month, and CPU (Intel Core i9 10920x) due a week later.

I don't feel the need to experiment with older Xeons right now... the 6850k will do just fine.

A RAM upgrade is the next item after changing to the new motherboard & CPU for me

@toasty99

The i7 6850k is sitting at a 4.4GHz lazy overclock speeds right now with a CPU Package Temp of 35C and Coolant Temp of 29C on the Corsair Hydro H150 at idlei. I score 7625 points in Cinebench R23 without tweaking things too much. Not a great score, but the system I built for my brother @ stock settings i7 8700k scores about the same... I know what brother doesn't want you to overclock the system you just built for him (LOL)...

Not bad for a 6 Core/12 Thread almost 10 year old hardware...
