well today I have what I believe is going to be a fascinating episode for you guys so let's start with video okay so videos everybody likes to watch videos there's a few people these days who own tablets there's a Motorola Xoom or smartphones there's an iPhone 4 and want to watch video on them but not all these devices and not all the media players are compatible with every kind of media that you that you download or rip or whatever however else you get your media so you often have to a transcode or convert the media from one format to another so I'm gonna be using media converter 7 for my testing today this is actually a really cool little piece of software it was 29.99 with a coupon code that I found very easily on their website ok so I'm going to be using a 200 Meg it is a three minute 1080p file that was actually taken with oh here you guys can see me this camera the sx1 is10 ATP I'm gonna be outputting it to an iPad compatible format and I'm gonna be doing it on a number of different platforms a number of different ways so I have three platforms I'm gonna use and I'm gonna be using kind of a best stuff until 11:55 so that's the z68 chipset with a 2600 K hyper threaded processor that is the most expensive platform out of what I'll be using today I have an AMD AM 3 platform I have a crosshair for formula with a 6 core 1100 T CPU bear in mind of course that the motherboard doesn't really have any impact on the performance in this case it's a CPU limited thing and finally I have AMD socket fm1 so this is their new APU socket so I've got a 38 50 quad-core apu here on an a 75 MHz 55 motherboard I'm gonna be using all the same hardware across these different boards and platforms so I'm gonna be using 8 gigs of ddr3 memory I've got same power supply and until 510 Series SSD on my test platform then on each platform I'm going to Inc transcode the video a different way so I'm going to use the CPU then I'm going to use a GTX 580 then I'm going to use a Radeon 6970 and finally I'm going to use the integrated GPU and we're gonna compare how all these solutions perform against each other whether we're using cpu CUDA Direct compute or in Intel 1155 s case virtue or the APU on AMD FM one let's see how it goes ok so my first two runs are done with the CPU as well as with the GTX 580 using CUDA on the 1155 platform and the one that I'm about to run and the reason I'm stopping to tell you guys about it is with lucid virtu so all I have to do is turn virtue on there we go the processor graphics are now enabled although I am plugged into the dedicated graphics card so the IGP is working now and I'm gonna run it with this one and see how it goes so I'll share results with you as I go here and as I discover what works better and what doesn't so here's a bit of an update I have the AMD FM one system running right now so I got most of my results done for that and I'm actually running it with the 6970 right now so you can see that the GTX 580 due to it's very high performance actually outperforms the CPU by itself which we expect I mean the CPU was the slowest out of all of our results even on the 11:55 platform where it's a significantly faster CPU with hyper-threading the IGP did beat the CPU but not maybe not by as much as I would like to see and actually here's something interesting I also added on the 11:55 platform I tested a gtx 550 to see how it would compare to the 580 so it's almost as slow as a cpu so and definitely slower than the IGP so if you're using 11:55 and a lower-end graphics part well with anything but a super high-end graphics card you may actually be better off with with virtue or using the CPU versus using CUDA so here we go we've got our result for the 6970 so here it is it is 133 so you can see the 69 70 once again doesn't perform quite as well as the 580 but it's close and then the IGP trails significantly behind those two due to it well being substantially slower so I'm pretty much finished my data at this point only to discover that it was all pretty much for nothing so what I accidentally did was I used a video file this one which had already been converted from its large high bitrate self into a Windows Media Audio files so what I'm gonna do second time around is I'll be using this one this is a one point six four gig file whereas this is a two hundred mega file by accident ok so this is a MOV file that is what is natively recorded by my camera then I'm going to convert this into an iPad format so you can see the data I've got here with the other file so the Intel Quick Sync is a good performer CUDA also performs quite well OpenCL is a little bit behind CUDA and CPU is invariably the slowest solution however I just ran quick sync on the new file which is the Intel Core i7 Extreme Edition 990 X or maybe it's a nine ATX unboxing and I was done in 56 seconds I am now running it on OpenCL and you can see the difference in performance between quick sync and OpenCL on that already transcoded once file this ran and yeah 56 seconds and it's already taken well over two minutes with OpenCL when we're doing a far more complicated file so I'm gonna just rerun everything which is gonna take me a look at the time it is now already which is gonna take me another you know hour or hour and a half or whatever and then I will be back with proper results for you guys okay well I'm finally done took me another couple hours to finish up here but I have the results so I've just used my old chart but all of the bottom results are the ones using the larger file and converting it to an iPad compatible format with media converter seven so let's have a look at the chart here and let's go we'll go through it together so this is the 2600 Kay with the CPU alone it clocks in at one minute 40 seconds which is better than the 1100 T better than the 38 50 and better than the i3 2105 so that makes a lot of sense because is more expensive than this which is more expensive than this which is almost the same as this so this one you can see due to its for course this is 2 cores with hyper-threading this is 6 cores for hyper-threaded course so this guy with this four cores performs better than the equivalently priced intel cpu with only two cores alright now let's factor in CUDA so we've got a GTX 580 now so they actually all perform fairly similarly this was a bit of a glitch but I ran it again and I don't know why but the 1100 T did not perform quite as well with my cuda GTX 580 as the the other cards did with the 6950 we seem to see a lot more benefit from additional CPU power so you can see that the 6950 is still an improvement over the CPU but it doesn't skin like CUDA was very similar for it with a GTX 580 across the board whereas the 6970 it seems like if you have a more powerful CPU to feed it it is really able to ramp up the performance so with the i3 2105 and clocked in at 246 with the 3850 226 209 with the 1110 of Wapping one minute 36 seconds with the 2600 K now IGP performance so the 1155 to the 2600 K and the 2105 were both within spitting distance of each other and in spite of this being a quad-core CPU that is clocked higher this being a dual-core CPU so you can see that the IGP is doing all the work here it's not getting a whole lot of help from the CPU side like we saw with the 69 50 as for the FM one solution remember unlike the Intel IGP with using a lucid virtu on the FM one solution you can only use it if you are running onboard video this can be used if you're using AC 68 or H 67 chipset there's my Z 68 board this can be used even if you are running a discrete graphics card so that's kind of a cool feature as well so here you can see that the IGP did not perform as well as the 69 70 but was still better than the CPU on its own so hopefully this was helpful thanks for checking my video on the different platforms and their video transcoding performance baron mao here's another quick thing to bear in mind you guys so you can see here that the with the age 67 or z 68 chips at the 11:55 chips whether it's an i7 or an i3 just smoke everything else but only a few software applications actually support all of these different hardware accelerations so if you're using anything that doesn't in terms of sheer CPU performance you can see that the FM 13850 due to its additional course blows away the equivalently priced product from Intel and then you have to spend quite a bit more to get better performance on the Intel site don't forget to subscribe guys
