AMD Carrizo Part 2: A Generational Deep Dive into the Athlon X4 845 at $70by Ian Cutress on July 14, 2016 9:00 AM EST
Stock Comparison: Office Performance
All of our benchmark results can also be found in our benchmark engine, Bench.
Agisoft Photoscan – 2D to 3D Image Manipulation: link
Agisoft Photoscan creates 3D models from 2D images, a process which is very computationally expensive. The algorithm is split into four distinct phases, and different phases of the model reconstruction require either fast memory, fast IPC, more cores, or even OpenCL compute devices to hand. Agisoft supplied us with a special version of the software to script the process, where we take 50 images of a stately home and convert it into a medium quality model. This benchmark typically takes around 15-20 minutes on a high end PC on the CPU alone, with GPUs reducing the time.
The higher IPC of the Pentium offsets the extra threads provided by the X4 845, which lags behind the other Athlons due to its reduced L2 cache size.
Cinebench is a benchmark based around Cinema 4D, and is fairly well known among enthusiasts for stressing the CPU for a provided workload. Results are given as a score, where higher is better.
For CineBench, we see the four threads of the X4 845 in action, easily pushing a strong advantage over the Pentium in the multithreaded test. However, the Pentium does pull a 33% increase in the single threaded test due to its higher IPC.
HandBrake v0.9.9: link
For HandBrake, we take two videos (a 2h20 640x266 DVD rip and a 10min double UHD 3840x4320 animation short) and convert them to x264 format in an MP4 container. Results are given in terms of the frames per second processed, and HandBrake uses as many threads as possible.
The Athlon X4 845 rules the roost in our HandBrake tests, showing what the latest AMD microarchitecture and four threads can do.
Hybrid is a new benchmark, where we take a 4K 1500 frame video and convert it into an x265 format without audio. Results are given in frames per second.
This also translates through to x265, where the dual core Pentium is lacking the ability to exploit more parallelism.

coder111 - Friday, July 15, 2016 - linkWow, another Asus A6 user. I still use my K73TA daily. Quite happy with it. Never tried overclocking, but now that you mention it I will.
How does the cooling hold up? I have had my laptop shutdown several times due to temperature getting too high after heavy APU+dGPU use.
I just wish there was a way to replace 6550M with something faster...
TheinsanegamerN - Friday, July 15, 2016 - linkRepaste the parts. The paste on that thing is half a decade old.
Also, undervolt the chips. You can cut a ton of voltage off of the CPU with k10stat.
If you really want to go DIY, there are those like me that cut a hole in the bottom of the laptop and put a grill over the fan, that lowered temps by about 20C for me.
coder111 - Friday, July 15, 2016 - linkHi,
Thanks for ideas! I'm on Linux, so I'll see if there are k10stat alternatives on Linux. I'll definitely repaste the parts. And I'll see if I can do the grill on the bottom as well...
coder111 - Friday, July 15, 2016 - linkCould you post the pics of your grill on the bottom somewhere?
TheinsanegamerN - Friday, July 15, 2016 - linkThat laptop is long gone, im afraid. The chassis did not hold up very well to my constant moving.
There was a forum on notebookreview about doing said mod, but the pictures are no longer available. the waybackmachine might be able to provide pics.
TheinsanegamerN - Friday, July 15, 2016 - linkI had the exact same laptop! I went with an a4 to force the dGPU, since AMD kept screwing up the ability to choose which GPU you wanted to use. 3.2 GHz dual core was amazing.
Sushisamurai - Thursday, July 14, 2016 - linkI like this pseudo-new review format. Very clean, and the shout out to manufacture/companies was a nice touch. I think u should include if the SSD's are MLC or TLC In that brief summary for those who forget.
keg504 - Thursday, July 14, 2016 - linkWhat does OCCT mean? It doesn't seem to be explained in the article

keg504 - Friday, July 15, 2016 - linkAh, thanks. A cursory search of google gave me many different results for OCCT
