Everyone talking about gaming performance, when it comes to content creation, Rendering and stuff. Vega destroys 1070.
"memory compression" not bandwidth or speed. Alex is referring to the tech used to store and transfer information to memory. the tech nvidia has that they developed for Maxwell is far more efficient than what AMD has. Allowing nvidia to use the memory and bandwidth more effectively than AMD which is one of the reasons why the performance between these cards is similar despite the Vega looking far more superior on paper and using much more power. remember that HBM also uses less power than GDDR5 and the 1070 is still more efficient.
Why tests vega56 vs gtx1080ti? It is very interesting to compare them )
You know that these are benched cards from before proper drivers. Technically prerelease versions. Specs can change before release or within manufacturing quarter. Memory software sucks so compression would slow a card down Schwarzenbach. Nvidia usually uses faster memory than their target card. Cooling efficiency is not about looks, it is materials used in the heat sink like copper transfer plate to high grade aluminum would be best, but the aluminum would be too costly. Most heat-sinks are made of mid to high-mid grade aluminum. The exterior cover is to direct air through the aluminum fins, slight ridges in the aluminum fins would help cool better than most flat fins too. AMD is very slow at maturing drivers, but usually makes the chips age far slower than Nvidia drivers or chips. Will be interesting as the R9 chip drivers are still not fully mature. Somewhat like Microsoft does with Windows without dropping support till fully matured. Nvidia makes too many design changes to do anything close without screwing up some added feature in their newer cards. Over all, who cares as long as it does what you want. Both companies make great cards. Nvidia has the speed and uses cheap and easy programmable stencil filler instead of a more realistic cut pixelation generator that is harder to program fast. These differences show up when blowing up the frame to max then zooming it in. Ether the Nvidia stops short or start looking pretty bad in comparison to AMD Radeon of the closest generation and value point. Probably the reason AMD takes much longer to mature as well. Sometimes the programmers look for stability over performance when there is a deadline. Just something to think about.
Are you stupid or what? Vega has a 2048 bit memory bus, the 1070 256 bit 409.6 GB/s vs 256.3 GB/s so vega has twice the effctive memory speed.
Average over 30 games the Vega 56 is the clear winner, doesn't matter which one is better for DX11 or DX12 outside of "future proofing" in which case vega 56 will only get better.
The stock cooler for nvidia's cards are way better which allow better thermals and performance. It will be interesting to see how much of a jump vega 56 gets once AIB cards start to show up. May even make the Vega 64 pointless.
Funny, reading this comparison it seems like the Vega 56 should completely destroy the GTX 1070. However when checking actual game benchmarks they are fairly similar. The Vega 56 might gain a lead once the drivers get better optimized. At the moment the GTX 1070 has the edge in DX11 titles while the Vega 56 gets the upper hand in DX12 and Vulkan.
