APU A4-5300 3.4 Turbo Boost Dual Graphics

Hi, Pardon Me I am New to forum support If there is any Spelling or Languages Mistake

I need a suggestions for my new build PC I am on tight budget but can spend extra.

My Recent PC Configuration is Below:

MSI - FM2-A55M-E33 Motherboard
Processor : 3.4 Ghz A4- 5300 APU with Readon HD 7000 Series Graphics
RAM: 8 GB - 1333 Mhz
PSU _ 550 Watt

So what I need Is to Upgrade my PCI GPU with Dual Graphics So What are the best GPU I can Buy for Dual graphics With this APU GPU. This MSI Motherboard Details Shows  Support AMD Radeon HD series graphics card* for dual graphics

But In market there is R Series available Can I use them or I should Stick With  Don't know Really need Help.

Re: APU A4-5300 3.4 Turbo Boost Dual Graphics


Hello, js_g. I made sever benchmarks some early times with AIDA64 shown on the above. AMD A4 5300 is an entry level processor, do not expect too much this processor, which is based on the the second revision of Bulldozer microarchitecture, Piledriver, codename Trinity for APU. It has a PCI-Express 2.0 x16 exported for external Graphics card, PCIe 3.0 card could work on this system, but working at PCIe 2.0 speed. For dual graphics (hybrid the APU and GPU), this processor does not support AMD Rx 2xx and later, only AMD HD7000 series are supported. For dual external graphics card, any two identical ones are supported.

In my benchmark, both A4 3300 and A4 5300 are using dual channel DDR3 1600 memory modules, Sempron X2 190 (one pin missing) using dual channel DDR2 666, while Intel Pentium E5200 using single channel DDR3 1333 (working at 800MT/s). Something could be seen obviously for AMD A4-5300,


Such as SSE4.1, SSE4.2, AEX, AVX, XOP, FMA3 and FMA4, those newly involved instruction set and comparably high frequency (3.4GHz vs 2.5GHz) would accelerate it on some specific computing, especially for AES-256.


A4-5300 has only one module, which has two slimmed integer cores, from 3 EUs(A4-3300/Sempron X2 190) down to 2EUs, sharing one float point unit. Even though the higher frequency could make up something, but its weakness exposes when test on Juila and Mandel computing. As to the integer computing, the slimmed down EU exposes its weakness on the 64-bit integer computing. The Core microarchitecture based Pentium E5200 has almost 4EUs inside making it at the comparably low system memory bandwidth but result in a higher score. Years ago, I have also benchmarked Celeron E3300, which has the same frequency as E5200, but half size of L2 Cache, 1MB. The results is similar.

Last but not least, I have mentioned one thing, the AIDA64 benchmark is high optimised for each processor. During the actual computing, especially for threads are distinct each other too much, the A4-5300 would give out a worse performance than A4-3300, for its modulelised design. But every coin has two sides, the queen side, alongside with Pentium E5200, it also could play H265 1080p at acceptable performance.

Best Regards,
