Strangely, they determine that AMD is more efficient.

PCI Express chipsets seem to draw more power than AGP core logic.

Because there is nothing more fun than mocking Toms these days, too many times they have been caught showing extreme bias, using flawed scientific methods, outright dishonesty, etc... And just as many times they have editorialized about how legit and forthright they are with their readers, and taken shots at other web sites as well. Toms deserves all the abuse we can muster, and more...BrianE wrote:I'm not sure what all the sarcasm is for....
What? I think tomshardware.com is great, and the VGA/CPU charts are the best by far.Because there is nothing more fun than mocking Toms these days, too many times they have been caught showing extreme bias, using flawed scientific methods, outright dishonesty, etc...

Most of my sarcasm was around the fact that the AMD processors soundly whupped the Intel processors (in both efficiency *and* performance), yet THG's conclusion was a rather tepid "choose whichever works for you" rather than "Intel's got some 'splainin' to do".BrianE wrote:I'm not sure what all the sarcasm is for.... just because this is something SPCR and more tech-savvy computer users already know, doesn't mean that everyone else knows it and that it doesn't deserve a closer look.
I think it's a good topic to write about because it actually discusses, tests, and proves the lower power consumption of AMD systems. I didn't read the whole article, but I liked looking at the test results comparing some power measurements, and if nothing else it's a good demonstration for public education.

Question 2: What is the efficiency of the power supply at different loads?

The power supply we used has an average efficiency of around 70% and can be considered a decent choice, although there are better ones around now.
Nice and scientific!

Its plain to see why SPCR is so highly respected when other hardware sites are still only scratching the surface on what is a time consuming and precise test.
While some of their comparison charts are useful they have been caught showing bias more than a few times in their stand alone reviews. Every word you read at Tom's should be taken with a huge grain of salt and validated by several concurring reviews.amplemind wrote: What?
