Kaveri Hybrid CrossFire: A10-7850K/7700K With R7 240 & 250

3DMark 11 and 3DMark (2013)

3DMark11

3DMark 11 is a DirectX 11 video card benchmark test for Windows that is designed to measure your PC’s gaming performance. 3DMark 11 makes extensive use of DirectX 11 features including tessellation, compute shaders and multi-threading. Download here.

With Dual Graphics enabled we see some solid scaling with both the R7 250 and R7 240. 70% for the A10-7850K and 55% for the A10-7700K. However, compared to a standalone R7 260X using the CPU on the A10-7850K there is a substantial gap which shows the advantages a GDDR5 graphics card has from all that memory bandwidth.

3DMark (2013)

The new 3DMark includes everything you need to benchmark your hardware. With three all new tests you can bench everything from smartphones and tablets, to notebooks and home PCs, to the latest high-end, multi-GPU gaming desktops. Download here.

3DMark shows a similar picture. Both APUs scale very well. Remember we aren’t expecting 100% scaling with the A10-7850K because the R7 250 has only 384 shaders, not the 512 of Kaveri, so in reality the maximum scaling we can get is 75%. The same applies for the A10-7700K – the R7 240 has only 312 shaders whereas the A10-7700K has 384 so we can only expect 81.25% scaling. In 3DMark (2013) we saw 61% scaling with the A10-7850K and 39% scaling with the A10-7700K.
