[Solved] What is the best single core CPU toor gete CPU to get?

The single core CPU that I can think of are:

AMD Athlon
AMD Athlon 64
AMD Athlon X2
AMD Athlon XP
AMD Duron
AMD Geode
AMD Opteron
AMD Sempron
AMD Turion 64
Intel Celeron
Intel Celeron D
Intel Celeron M
Intel Core Solo
Intel Itanium
Intel Pentium
Intel Pentium 4
Intel Pentium 4 Extreme Ed.
Intel Pentium 4 HT
Intel Pentium D
Intel Pentium III E
Intel Pentium M, Centrino
Intel Pentium MMX
Intel Xeon
Intel Xeon MP

The best single core cpus are the celeron D 450 (when oc 3ghz+) and the Sempron 140.

Well, overall, the Sempron 140 is the best. Decent power consumption.

Icey cold when you touch it too...

Yes, they do.

Celeron Ds are really old.

Like my grandma. Maybe not. They are harder to find these days and cost about the same. The Sempron wins in performance hands down. Sempron sips less power too

nForce, I didn't understand your post. Anyway, theSempron 140 has:

Clock Speed2.7ghz
Hypertransport
4000mhz
L1 Cache
128kb
L2 Cache
1mb
Manufacturer
Advanced Micro Devices, Inc
Manufacturer Part Number
Sdx140hbk13gq

The 140's specifications:


Amd Sempron 140 2.7ghz 4000MHz HT 1MB L2 Cache Socket AM3 w/ 64-bit Processing, AMD64 Technology, & Thermal Design Power of 45W

Hmm.... even though your looking into the fastest single cores maybe you should into intel cpu's like the core i5, i7-860, or, i7-870.

Yes there quad cores but when working on single threaded application these cpu will activate turbo boost. Increasing the GHz.

The core i7- 870 when turbo boost activates will go from 2.9 ghz quad core to 3.6 ghz single core.

Not saying you should go for an i7 or an i5 but just somthing to think about.

its not just mhz you want a high IPC also

I'd still consider a modern dualcore intel, you can always disable a core or let it idle.

I also recommend the Sempron 140. I have yet to try it, but if I build another system, it will be using the Sempron 140. Currently, my main computer uses a Celeron 420 @ 2.66GHz/1333 fsb. With c1e it idles at 2.0GHz. My HTPC uses a Sempron Le-1100 barely overclocked to 2.0GHz, but spends most of it's time idling at 850 MHz. I've had a D 805, an e2160, e5200, X2 BE-2400, and X2 6000, but my needs were better served by single core CPUs, so I went back to my old stalwarts and have enjoyed the energy savings ever since.
