I agree that they should also included multi-threaded tests, that show how well a CPU handles multithreading (IPC - Interprocess Communication), message-passing, cache-line-sharing, etc.
But there's a limitation on how well multi-cores can scale, due to Ahmdal's law, so single-threaded performance is ALWAYS important.
That's because it IS WEAK. Why do you think AMD charges less for their CPUs than Intel? Just because AMD is such a nice company? No! They have to, they have less performance.
LOL AMD uarch is NOT WEAK. Theres a reason that there exists an unfortunate unquantifiable difference between intel and AMD's CPU's perceived smoothness in operation when doing multiple tasks at once. Ive have seen many accounts and heard many accounts of people stating their AMD system just feels and plays smoother than a comparable intel one. Hence why its unfortunate so many sites dont do true multi tasking reviews...and its nearly impossible to test the "smoothness" of a system.
Just because a system can pull 100fps+ in a game doesnt mean its running "smoother" than a 40fps system. I and many others can attest to this.
Also, much code is unfortunately written for optimization on a intel uarch rather than being equally as fair to a AMD CPU. Hell, half the benchmarks in existence are rigged for this.
AMD gets bad press, gets bad bench results all because of this. THAT is why they have to sell their stuff for less.
Now, I am not saying AMD's uarch is the one and only, all powerful, alpha and omega of CPU's...they arent as strong as intels in some areas, specially some technical areas on paper. But, some areas they are equal or better, especially in code optimized for AMD - which is RARE.
Imagine a world where code was written specifically tailored to their uarch, much like most code in existence is for intel uarch. The playing field would look SIGNIFICANTLY different. If code was completely unbiased between one or the other, it would still look different then it does now.
Given the way intel slants everyone in the industry towards optimizing for their uarch, I think AMD is doing a damn good job at keepin in the race.
