This thread is to test whether lower clocked (1.8G base clock) Xeons can run modern games or not.About this Xeon E5-2675v3:
This is an OEM chip made for big tech companies, such as HP and Oracle for their cloud servers and client workstations, however, this is also available on eBay for a reasonable price, even cheaper than the hexacore 5930K actually.
It features 16 cores/32 threads
It has a base clock of 1.8 GHZ and turbo clock up to 2.3 GHZ.
L2 cache: 4MB
L3 cache 40MB
This chip is compatible with most X99 motherboards and LGA-2011v3 server/work station boards.
It works with my ASUS X99-Deluxe and Asrock X99 Professional.Testing Platform:
E5-1660v3( i7-5960X equivalent and better binning) at default clock 3.0/3.5 Turbo. Retail for $1080
ASUS X99-Deluxe U3.1
Powercolor R9 290 4GB x 2 (Games are tested in single card since I RMA one of them)
ADATA 4 x 8G DDR4 2400
Samsung 950Pro 512GB
Resolution: 4096x2160 or 3840x2160, depends on game.
OS: Windows 10 ltsb x64
CPU: disabled C-States, EIST, and ASUS EPU.
1. Theoretical Performance:
Maxxon Cinebench R15
The forum squeezed the image a bit.
4.4GHz i7-4770K:822cb2.Battlefield 4
4096x2160, High, Vertical sync. Same scene in game (Zavod 311)
It seems that this game is optimized up to 8 threads. (Please correct me if I am wrong)
We can see that higher clocked E5-1660V3 performs a bit better than lower clocked E5-2675v3 by 10%, but 2675 will not bottleneck the game performance by any mean. Higher clocked 4.8G 4770K/4790K/6700K will perform even better for this game.3. Star Wars Battlefront
4096x2160, Ultra, Vertical sync. Same scene in game.
It seems that this game is optimized up to 12 threads. (Please correct me if I am wrong)
The weird thing is that the lower clocked 2675 performs even better than the higher-clocked 1660. I tried 4 times, and the results are similar.
4. Assassin's Creed: Unity
3840x2160 High, Vertical sync. Same scene in game (The last quest)
It seems that this game can use all 32 threads!!! (Please correct me if I am wrong)
The FPS spikes are caused by insufficient VRAM I suppose, but we can tell basically no difference in terms of average FPS.
More games and software testings are coming soon.
