Take a look at uncore overclocking, as I believe the cache is considered part of the uncore:

bumping this thread because if anyone who actually knows can answer, then I think I could learn something. I have no idea why you can't OC cache; in fact cache OCing is not something I'm very familiar with at all; I had always assumed it overclocked along with the rest of the CPU these days.
Oh trust me, I have asked them. Many times. It's in IP hell right now because Cyberstorm was a Sierra produced game developed by Dynamix. Both of those companies are now defunct; as a part of the Starsiege universe, the IP was defacto purchased by HiRez Studios (of Tribes: Ascend fame/infamy)...
This is what actual 3 core performance looks like (Tomb Raider, same machine as last time, no TressFX):

I think I see the confusion now. I should not have used the word "test" so liberally in the OP. The real reason I ran the game on these three systems was to get a general idea of the performance of each rig as I was purposing them, not to see what kind of engine was under the hood with CSGO. I...
Actually, the OS differences are a help to the test, showing us that it is actually unlikely to be a scheduling issue - two different scheduling mechanisms showing basically the same result is no accident of a particular software.
FPS was not really important for this test since both were GPU...
I hear you man, I also still have my original CD with no DRM and everything... Gaming was different back then, haha. Anyway, I run this game without issues in XP mode or an XP virtual machine with a few compatibility settings turned on. There's even a patch for cybrid return fire, which makes...
25% load total tells us very little unfortunately. That could be two threads at 100%, or it could be all 8 of your threads at some fraction, or it could be something in-between.
All evidence points to CSGO not being on Source 2 engine, but I can tell you right now that the game looks like it...
You have four additional threads, but also a much faster core and wildly different RAM and probably I/O as well. Can you tell us what the load per thread was, and the number if threads used?
