Great article Gavric!
This goes to show that clockspeed would have been much better for AMD than the huge cache and even the 6 cores if we're talking about the desktop/notebook market. On the servers market, I guess that the 6 MB L3 Cache was quite necessary and the 6 core are really proving their worth even against the Nehalem based Xeons. On the desktop side however, give me a 3,8 Ghz Phenom II without any L3 Cache any day against any Core 2 Duo and a 4 GHz Phenom II w/ 4 MB L3 Cache against the Core i7 series and I'll open my wallet! Still, there is a point to be made about using a DDR3 memory controller with at least 1333 MHz speeds. DDR2 667 MHz is really slow these days, especially against the Triple Chanel Core i920 DDR3. AMD really needs a new server platform. If we can get 5% more performance from using DDR3 1333 MHz unbuffered memory and 5% more from using a newer platform, we get roughly a 11% performance bump on the so called Thuban platform. So, adding 11% more performance would make a Thuban corresponding to the Opteron 2435 faster than the 3,4GHz Phenom II 965 in the following benchmarks : PCMark Vantage, 3D Mark Vantage, DivX 6.8.5, x264, CyberLink Media Show, Adobe premiere, 3D Studio MAX 2009, CINEBANCH, Maya, WinRAR, Resident Evil 5. Only in Adobe Photoshop and some games would Istanbul still be slower than the 3,4 GHz Phenom II 965 but only around 4% ~ 5% slower while the Phenom II 965 has a 30,7% higher clockspeed.
