x264 HD Video Encoding Performance
Graysky's x264 HD test uses the publicly available x264 encoder to convert a 4Mbps 720p MPEG-2 source. The focus here is on quality rather than speed, thus the benchmark uses a 2-pass encode and reports the average frame rate in each pass.
Video encoding is going to favor Hyper Threading and more cores, both of which the Pentium G6950 lacks. The win here goes to AMD's Athlon II X3 440. Even the higher end Clarkdales don't make any sense as the Core i5 750 offers a tremendous value.

"It's GPU still only runs at 733MHz though"... "It's" is not quite right... Take care.8steve8 - Thursday, March 25, 2010 - link
why was the G45 omitted on pg2 in the graph of power consumption under load with integrated graphics?I was keen to see how much more efficient HD graphics were than g45.

It would have been nice to see the benchmarks run with the overclocked G6950 also.- Brian

I have a hard time comprehending what Intel/AMD's TDP ratings mean in light of the "Load Power Consumption" graph.How is it that Intel CPUs with higher TDP ratings consume MUCH LESS power at load than AMD CPUs with lower TDP ratings. Just looks at the results -- all of the Intel core i3/5 CPUs are 73W TDP but the Athlon X2 255 is rated at 65W yet consumes 20 more watts at load. Is the 790FX motherboard that inefficient? WTF???
Lower idle consumption for Intel I understand due to the smaller process and excellent design, but do the TDP ratings truly mean nothing? This is a disastrous result for AMD.

Both companies rate their TDP differently, and in either case it is not designed to be a measure of power consumption.Nickel020 - Thursday, March 25, 2010 - link
It would be nice if you could include the 661 in the power consumption charts. Does its higher TDP actually lead to higehr power consumption?Sunburn74 - Thursday, March 25, 2010 - link
If you're gonna talk about the value of a 4.4 ghz overclocked processor, you gotta include it the benchmarks. Duh!crochat - Thursday, March 25, 2010 - link
Why the hell is it necessary to always put discrete graphics card in systems with integrated graphics and do power consumption tests with it? Is the benchmark used for power independent from the graphics card?I understand that it is much simpler to measure watts only, but what is important is the resulting task energy consumption, taking into account the efficiency of the processor..

Because some of the tested systems don't have integrated graphics. So for the application performance comparisons shown to be valid, the discrete GPU has to be kept in there. Wouldn't want someone thinking they could get 69.1 FPS in Crysis Warhead with the power consumption of only the integrated graphics.Taft12 - Thursday, March 25, 2010 - link
It's necessary to save many hours of work the testers could spend on more articles. What counts is the delta in power consumption between CPUs/platforms at idle and load.I'm an AMD fan, but the bottom line is Intel systems are more power efficient, period.
