The Radeon HD 7310 and the HD 7340 are the integrated graphics in the AMD’s Brazos 2.0 Accelerated Processing Units ( APUs) that were launched around June 2012. The Brazos processors have been very successful for AMD as these are much better than what Intel has to offer with its Atom processors. While AMD did ship close to 50 millions of these chips, they have not been able to make much profit on it because they have been priced ultra low.
The two APUs that have the HD 7310 and the HD 7340 are the E2-1200 and E2-1800 respectively. Let us take a look at the complete APUs with special focus on their graphics capability.
Table : Feature Differences
|Feature||HD 7310||HD 7340|
|Base Clock||HD 500 MHz||523 MHz|
|Turbo Clock||HD 500 MHz||680 MHz|
|Processor Core Frequency||1.40 GHz||1.70 GHz|
|Procesor No. Of Cores||2||2|
Essentially, AMD paired these processors with the two Brazos 2.0 APUs. The E-series APUs, use the same die that original Brazos (E-450, E-350 and E-300) APUs used. All AMD did was bumped their clocks a little bit for processor as well as the graphics and rebranded them. The Graphics in the original Brazos was termed as HD 6310/6320 and have been rebranded into HD 7310/7340 with clock frequency Bumps. There is no change in the silicon or the die. The rebranding of the 6300 series into 7300 series may (mis)lead you to believe that they are next generation high performance newer graphics core, but in reality they are not.
The E-300 clocked the HD 6310 GPU in it at 488MHz, 12 MHz slower than the E1-1200′s 500 MHz. Similarly the earlier E-450 had the base GPU clock at 508MHz n it 6320 GPU that has been bosted to 523 MHz in the HD 7340 in E2-1800. So do not expect any major performance improvement just because their names imply.
In the next page we will take a look at some of the benchmarking results and will compare it against other graphics.
