The AMD Radeon RX Vega 64 & RX Vega 56 Review: Vega Burning Bright
by Ryan Smith & Nate Oh on August 14, 2017 9:00 AM ESTGrand Theft Auto V
The other veteran from our 2016 GPU game suite, GTA V is still graphically demanding as they come. As an older DX11 title, it provides a glimpse into the graphically intensive games of yesteryear. Originally released for consoles in 2013, the PC port came with a slew of graphical enhancements and options. Just as importantly, GTA V includes a rather intensive and informative built-in benchmark.
Like its previous appearances, we follow those settings, as GTA V does not have presets. To recap, for "Very High" quality we have all of the primary graphics settings turned up to their highest setting, with the exception of grass, which is at its own very high setting. Meanwhile 4x MSAA is enabled for direct views and reflections. This setting also involves turning on some of the advanced rendering features - the game's long shadows, high resolution shadows, and high definition flight streaming - but not increasing the view distance any further.

Exactly. I REALLY want to run my games in a VM guest.sutamatamasu - Monday, August 14, 2017 - link
In RTG slide on architecture side. Vega have some MB SRAM. Can you tell me what this SRAM use for?DanNeely - Monday, August 14, 2017 - link
Various caches and internal buffers; on die memory is normally SRAM because it's several times faster than DRAM. (DRAM is several times denser since it only uses 1 transistor/bit vs the 4(?) for SRAM; which is why its used for main memory where total capacity is more important - and where the data bus is the main latency source anyway.) I'd be curious what the breakdown is since only 4MB if it's in the L2 cache.sutamatamasu - Monday, August 14, 2017 - link
Yes, same with me. Like we all know GCN 5 has no change on L2 Cache size but i am curious, AMD say this SRAM and L2 Cache size differently.extide - Monday, August 14, 2017 - link
A lot of it is going to be in the low level L1 caches and stuff local to the shaders -- there are a lot of shaders, so it will add up fast. GCN 5 does have double L2 cache, at least according to this article, 4MB vs 2MB. AMD says there is a total of over 45MB of SRAM on there, which is pretty impressive for a GPU!ratbuddy - Monday, August 14, 2017 - link
I'm disappointed that Vega Frontier results were not included in the benches :-/Ryan Smith - Monday, August 14, 2017 - link
AMD did not sample that card, and there's not much of a reason for us to include it now when the RX Vega is faster.Nfarce - Monday, August 14, 2017 - link
Another Fury X fail. You'd have to be a hard core AMD fan to buy this over a GTX 1080, and that's not even taking into consideration the horrid power use compared to the 1080. Isn't that what AMD fans tell us is so important when comparing Ryzen to i7 CPUs in core/watt performance? Amazingly they are silent here.IchiOni - Monday, August 14, 2017 - link
I do not care about power consumption. Only poor people care about power consumption. I will be purchasing an air cooled Vega 64.Hurr Durr - Monday, August 14, 2017 - link
So Barnum was right in the end.
