Are these CPU's really as bad as I am Reading about in reviews etc ? If I had it overclocked to say 4.2-4.3Ghz and put it with a Decent Dx11 Video Card . Played at 1024 X 768 (Only) /w 4AA & 8 AF . Do you think this card would still have problems playing a CPU Demanding/Intensive game (Such as Crysis , BF2/3 etc )
I Read things like the AMD Athlon X2 4400+ /w only 512k L2 Cache beating up this Processor in such games . and the 4400+ is only 2.2ghz , is this TRUE ?
I know Cache , FSB Speed , and Instruction Sets are the most Important things these days (Compared to Raw MHZ Power)
But you would think a Duel Core 4.25Ghz CPU (From any Generation) Would be able to Handel any game without choking ..
I Love Intel Stuff.. I just got 2 Intel Servers too (1 of them /w 2X 1400 (s) CPU's , and 1 of them /w 2 X 1266Mhz (S) CPU's) Haven't had much time to play with them yet but im sure they will still be useful
Disappointing to keep reading bad thing after bad thing
For the most part, everything you are hearing is right. The Pentium D is two Pentium 4s. It's a dual core Pentium 4. While a lot of the negativity makes it seem like there's nothing right about it, it was still a pretty unfavorable CPU. It ran warm, drew a lot of power, and was slower than the competing Athlon 64 and Athlon 64 X2, and it's even slower today. It was clocked high because it had to be to compensate for it's low IPC. That is, it may be at 4.3 GHz, but a 4.3GHz Pentium D is no 4.3GHz modern CPU, and the cache and FSB isn't why. Believe it or not, the Pentium 4 had a lower IPC than the Pentium III before it! (at least this was true for the early Pentium 4s, latter ones with higher FSB/cache might have overcome it) The architecture/design is why it's slower than modern CPUs, not instruction sets and whatnot. Plain and simply, the Pentium 4/D is just too poor and old to handle modern intensive stuff well even if you clock it to 8GHz.
I would not pair it with a modern Direct X 11 GPU that is respectably fast. It will bottleneck it beyond belief. It'd bottleneck a GeForce 8800 series GPU for that matter. The higher end Radeon X19xx or higher end GeForce 7 series is about the most I'd pair with it and not expect it to bottleneck to a high degree. I had a GeForce 6800 GS paired with my Pentium 4 2.8GHz w/Hyper-threading, and they felt roughly evenly matched (maybe the CPU being a slight bottleneck even).Edited by Princess Garnet - 12/2/11 at 11:07pm
