I can get some Opteron 4284s (8x3.0GHz Bulldozer) for $200 each, is it worth swapping out my Opty 4184s (6x2.8GHz Lisbon)? This box was mainly built for some GPU F@H and running LOTS of EveO clients. It just got built, so I haven't gotten around to testing performance under EveO with 10 fullscreen clients, but it's probably going to chew my CPUs apart.
With the 4184s it does destroy my 8120 @ 4.3GHz in almost every benchmark I've run though, so that's encouraging. 6 EveO clients was the comfortable max with the 8120 OC'd. So main uses are multi-box gaming, gaming, F@H, video encoding, and running some Linux VMs if I'm doing work. Unfortunately HyperSLI doesn't seem to work with either dual CPUs or this motherboard, so running a regular gaming scenario can sometimes suck at the moment. I also play some STO and WoW, and will be playing Star Citizens when it goes beta (CryEngine 3 based).
System build is currently 2x 4184, Stock AM3+ coolers, 16GB (4x4GB) Ballistix RAM, Tyan S8225 dual C32 motherboard, 2x EVGA GTX 660 SC, 2x GTS 450, SeaSonic X850, Chenbro Tesla RM41300-FS81 4U case, OCZ Vertex 2 60GB OS/small app drive, OCZ Agility 3 120GB app drive.. mass storage is over GigE to an AMD E-350 Slackware machine with 6x640GB 2.5" drives in RAID6 and an Intel 82571 dual GigE nic. I am switching the 660 SCs out for GTX 670 FTWs, and eventually the GTS 450s for something else with a blower HSF.
So basically is a 3.0GHz Bulldozer 16-core system better in lightly threaded tasks than a 2.8GHz Lisbon 12-core? If the scheduler is smart (and I don't know if the Win7 one IS smart), I could theoretically run up to 8 threads at max turbo frequency of 3.7GHz. I understand that if only 4 cores are loaded per CPU they'll hit 3.7GHz, is that correct? If so, even 4 threads at 3.7GHz should beat Lisbon at 2.8GHz, no? That would be a typical gaming scenario for WoW/Star Citizens.
How about heavily threaded tasks (ie video encoding/F@H)?
I'd really like 4386s, but I have a feeling I'm not going to find them in this price range. It's hard to find benchmarks, even the 1045T benches have turbo core enabled, so I don't know how these two CPUs really compare.
