AMD Carrizo Part 2: A Generational Deep Dive into the Athlon X4 845 at $70

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 R15

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 x265

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.
