C2D 6420 vs C2Q 6600 Quad Vs. Dual Comparison

Testing and Comparison XP Vs Vista Quad Core

Since I had all that data anyway I figured why not combine it to get an idea of the C2Q performance using Vista and XP. So basically here’s all the same results you’ve already seen, but just using the Q6600 to get an idea of how well each OS handles a quad core processor.

So, here we are again with more tests, I think these though give you a much better idea of the performance or lack of when using Vista or XP with a Quad Core processor.

3dMark06

Hmm, well we won’t be breaking any records using Vista now will we?

FarCry

Here again we see better performance in Windows XP.

SuperPi

and yet again we see better performance under Windows XP, better but not much really..

TMPGEnc

Same, Same.

And here we are with Sandra to finish all this up… (insert blatant sexist joke here)

SiSoft Sandra Cache and Memory test

Benchmark the processors’ caches and memory access (transfer speed).

Combined Index: is a composite figure representing the overall performance rating of the entire Cache-Memory performance in terms of MB/s. . (Higher is better, i.e. better performance)

Speed Factor: is a figure representing the speed differential between the CPUs cache and memory. (Lower is better, i.e. the memory is not very much slower than CPUs cache)

CPU Arithmetic Benchmark

Benchmarks the ALU and FPU processor units. Shows how your processors handle arithmetic and floating point instructions.

Results Interpretation : Higher index values are better.

Here we see better score for XP also, there seems to be a trend here.. I’m sure hoping Vista Service Pack 1 will make some needed improvements..

Processor Multi-Media

Benchmark the (W)MMX, SSE/2/3/4 processor units.

Results Interpretation : Higher index values are better.

and again XP is the choice here

Memory Bandwidth Benchmark

Benchmarks the memory bandwidth of your computer.

Results Interpretation : Higher index values are better.

but here we see Vista handles things better…

Memory Latency Benchmark.

Benchmark the latency (response time) of processors’ caches and memory

Results Interpretation : Lower index values are better.

Here it’s a toss up, depends which you want the most I guess…

Multi-Core Efficiency

Inter-Core Bandwidth :Results Interpretation : Higher index values are better.

Inter-Core Latency :Results Interpretation : Lower index values are better.

Well, here we see Vista is actually the better choice… just kidding, there’s not much of a difference really to call a clear winner
