Some time ago, appeared information that the graphics processor Hawaii actually contains hidden potential as a number of disconnected computing units.
Enthusiast named Daeguen Lee decided to try to predict the performance level of the full Hawaii version . So, GPU computing is attributed to the presence of 48 units, for a total of 3072 stream processors and 192 texture units and 64 blocks ROP, 512-bit memory interface. Also, it is assumed that the hypothetical card based on the full Hawaii will operate at frequencies 1000/5000 MHz core and memory respectively. Note that the simulation performance is made using the program .
Increasing the number of stream processors and texture units to 3072 units and 192, respectively (ie, approximately 9%) increased the speed by only 2.5%:
The data for Radeon R9 290:
If slightly increase GPU clock then you can achieve a gain of 4% relative to the performance level value of the Radeon R9 290X:
Overclocking memory adds a little more performance:
There are rumors that AMD will use broadband memory (HBM), so enthusiast also tried to simulate a video card with this memory on board. The result was more interesting: 21% in the case of two-layer modules HBM (2 layers of memory and logic layer 1) and 26% in the case of four-module (4 layers of memory and logic layer 1).
