K Primitive Discard Acceleratoru:Starting with 3rd and 4th-gen GCN, however, the HWS makes it possible to virtualize these compute queues. This means that any number of queues can be supported, and the HWS will assign these queues to the available ACEs as slots became available.
Each ACE block in the Polaris and GCN Architecture diagram(s) represent a single wavefront/workgroup dispatcher. Accordingly, the “Fiji” GPU and GPUs based on the Polaris architecture can dispatch up to four wavefronts/workgroups to the shader engines from any compute queue at any time.
The HWS units are dual-threaded microprocessors capable of handling two scheduling threads, and their behavior can be tuned with microcode updates by AMD.
The screen space is partitioned to load balance between the geometry engines, which can each rasterize a triangle per clock...
... The Polaris geometry engines use a new filtering algorithm to more efficiently discard primitives. As figure 5 illustrates, it is common that small or very thin triangles do not intersect any pixels on the screen and therefore cannot influence the rendered scene. The new geometry engines will detect such triangles and automatically discard them prior to rasterization, which saves energy by reducing wasted work and freeing up the geometry engines to rasterize triangles which will impact the scene...
In a similar vein, the Polaris geometry engines can detect triangles that have no area, and discard them during the input assembly stage. As vertex indices are read from the input buffer, the Polaris geometry engine will check if two or more vertices have the same coordinates (i.e., degenerate triangles). The degenerate triangles are culled before they are passed to the vertex shaders, which increases throughput by reducing the amount of work done and reducing the energy consumed...

Nejaky odkaz na realne predaje rx480 v tom ocuk? Ale nepocitaj predobjednavky ktore tvoria asi 80% tvojich odhadovKrteq píše:Ano, na jednom německém e-shopu. Na OC.uk to mají zase naopak a RX 480 je u nich nejprodávanější kartou vůbec.
Ber taky v potaz, že Polaris karty byly vydány o pár měsíců později oproti GTX 10x0.

ETA's updated as I literally just ordered an additional 3000 units of Nitro cards, infact the Sapphire Nitro 4G and 8G OC are as of now OcUK's pretty much top selling cards out of all graphics cards. Sapphire are absolutely over the moon with this level of success as are AMD.
But the Nitro at £199 and £250 is a serious incredible card that really just hits every mark, great looks, cool and quiet, tonnes of features, overclockable, great warranty. Gotta be one of the best all round cards of all time, absolutely nailed it! ...
...Sapphire manage to get us more than the promised 30pc early delivery, it is now around 100 units which all being well should ship today. This 100 is mixed between 4G and 8G however.
Next lot just shipped today, which was a further 60-100 units and hopefully more will ship this weekend.
AMD are also aware that we have nearly 10,000 units of RX 480 on backlog, of which Sapphire accounts for over 50%, as such AMD are also moving more GPU to fulfill OcUK PO's.
We are now no.1 in the world for RX 480 sales on an end-user based level. Right now we are actually turning away mining orders on RX 480 to ensure it is gamers getting first dibs.
As mining is kicking off again on RX 480, but we are refusing to take orders until there is enough stock to cope with gamers and mining demand, gamers come first....
...It really is, RX 480 is selling insanely well now, Sapphire with Nitro have nailed it and were finding the Powercolor Devil card to also be selling like crazy...
...We have customers trying to order several hundred at a time for mining, we don't ask them why or their reasoning. But GPU mining is still going on for sure!
Until stock improves we simply informing them we cannot do large trade orders.
Into your face haters
