[font=Arial, sans-serif]This was a lot of fun to digest. Thanks so much!. I know I love seeing the extreme boundaries, even tho they may not be so relevant to my own reality.[/font]
[font=Arial, sans-serif]I am not a gamer; but an artist/student of motion graphics & visual effects. Guys with the skills I'm learning build the games, the commercials, the movies, the broadcast graphics... Boring workstations heve been my life. My activity on a box mixes high resolution digital video, photos, 3D modeling, 3D animation, 3D motion tracking, and compositing. And my workflow demands hefty snap in real time tool response, previewing, and rendering. The proven gaming strategy of overclocking i7s/RAM, and stacking up multiple cuda GPUs would only get me so far.[/font]
[font=Arial, sans-serif]A solid WS strategy calls for a beefy balance of lotsa cores, lotsa RAM, SSD caching, RAIDed HDDs, a high-end GPU with "Adobe-blessed NVIDIA sensibility",and effective tweaking of graphics apps for performance. [/font]
[font=Arial, sans-serif]It's clear to most that a WS improves with the number of cores; but there is an interesting dilemma there. Graphics peeps fortunate enough to have a lot of cores (8+) can't often use them all. Oftentimes they encounter a phenomenon where applying too many cores actually slows their processing down (e,g, Adobe apps like After Effects). This happens when threading spawns many instances of a graphics program and cores begin to step on each other's toes as they compete for inadequate RAM. Installing more (and faster) RAM helps; but the biggest problem is that the multi-threading strategies the apps are coded with are inadequate or nonexistent. Benchmark apps are better in this regard, so they aren't as real world as we'd like. To their credit Adobe and others do enable their code to be assisted to some extent by OpenGL, Open CL, and Cuda processing in GPUs. But rendering is still not what it could be yet. So talk of processing cores and NVIDIA's Maximus schemes are really more tantalizing than satisfying to me. In spite of this, there still are reasons to invest in lotsa cores: 1) a typical graphics workflow requires many hefty apps to be open and processing simultaneously, 2) some rendering apps are threaded decently enough to capably use how ever many cores you enlist, and 3) multi-core machines built today will be able to fight obsolescence admirably as more and more apps jump on the multi-threading bandwagon.[/font]
[font=Arial, sans-serif]The system in the above test would problee make my life a whole lot easier!! But unfortunately I'm on a lower budget and looking to build a WS. Here's what I'd really love-LOVE to see at Overclock3D (and I'm sure you've thought of it already...) I'd love to see a more practical shootout based on the cost/performance expectation of the more typical graphics grunt. Maybe start with a baseline single CPU config based on the E5-2687w tested here, and then compare it to the same amount of cores achieved by a dual E5 Xeon config that costs roughly the same. And for good measure throw in a config that's cheaper but has even more cores....[/font]
[font=Arial, sans-serif]Certainly we're still talking more cost here than the high-end gaming MoBo/CPU, but less cooling. And how awesome would it be to experience the effectiveness of Intel QPI, plus chew on the subtle differences in CPU cache and clock-speed! Here would be my contenders:[/font]
[font=Arial, sans-serif]------------------------------------[/font]
[font=Arial, sans-serif]1) Single CPU, 8-core (baseline)[/font]
[font=Arial, sans-serif]Single E5-2687w Xeon CPU ([/font][font=Arial, sans-serif]8 core, 3.1 – 3.8 GHz, 150w, 20MB cache)[/font]
[font=Arial, sans-serif]ASUS P9X79 WS motherboard[/font]
[font=Arial, sans-serif]Cost: $2280 US[/font]
[font=Arial, sans-serif]------------------------------------[/font]
[font=Arial, sans-serif]2) Dual CPU, 8-core[/font]
[font=Arial, sans-serif]Two E5-2643 Xeon CPUs [/font][font=Arial, sans-serif](4 core, 3.3 – 3.5 GHz, 130w, 2 QPI Links, 8GT/s, 10MB cache)[/font]
[font=Arial, sans-serif]ASUS Z9PE-D8 motherboard[/font]
[font=Arial, sans-serif]Cost: $2370 US ($90 more than the baseline strategy)[/font]
[font=Arial, sans-serif]------------------------------------[/font]
[font=Arial, sans-serif]3) Dual CPU, 12-core[/font]
[font=Arial, sans-serif]Two E5-2630 Xeon CPUs ([/font][font=Arial, sans-serif]6 core, 2.3 – 2.8 GHz, 95w, 2 QPI Links, 7.2GT/s, 15MB cache)[/font]
[font=Arial, sans-serif]ASUS Z9PE-D8 motherboard[/font]
[font=Arial, sans-serif]Cost: $1820 US ($460 less than the baseline strategy)[/font]
[font=Arial, sans-serif]------------------------------------[/font]
[font=Arial, sans-serif]AGAIN, Thanks for the very intriguing & enlightening test. Very helpful for us WS peeps![/font]
