We are on the eve of launch and the first (final) benchmarks of the RX Vega family have leaked out from Chiphell (via Reddit). The benchmarks in question show the aggregate performance of the RX Vega 56 and RX Vega 64. It is unknown how many games and/or synthetics were used to perform the aggregation but they do look eerily similar to the template of a very well known Chiphell reviewer who I will not name for obvious purposes.
Radeon RX Vega 64 air cooled variant is faster than the GTX 1080 FE, Vega 56 faster than the GTX 1070
More interestingly, they help us set our final expectations for the upcoming launch tomorrow, not to mention the positioning of the Vega 56 and Vega 64. Without any further ado, the benchmark is given below. Keep in mind however, that the comparison is being performed with reference cards and not AIB custom variants:
We can immediately see that the RX Vega 56 can indeed outperform the vanilla GTX 1070 (this is something we weren't very clear on) and probably custom AIB variants as well. This is great news, because priced at $399 it will be able to go head to head with the GTX 1070 - and if these benchmarks are any indication - even win.
The RX Vega 64 Air Cooled variant is just faster than the GTX 1080 FE but much slower than the GTX 1080 Ti. This is great news however, because it confirms that AMD's RX Vega 64 will be able to give a great value proposition and go head to head with the GTX 1080 - even the air cooled edition. Since the liquid cooled variant will naturally have higher clocks, we can expect it to be even further ahead and maybe even approach the GTX 1080 Ti's performance class.
Both cards will be launching very soon so stay tuned!
Vega 56 and 64 overview
The RX Vega 56, as the name suggests, has 56 CUs with a stream processor count of 3,584. The Radeon RX Vega 56 will also feature 8 GB of HBM2 VRAM which will deliver a rated bandwidth of 410 GB/s along a 2048-bit bus interface. It will be using HBM2 just like its big brother and will retail for $$399. The chip will feature a total compute horsepower of 10.5 TFLOPs (FP32) and will feature a TDP of 210W which will be provided through an 8 and 6 pin power connector configuration.
This means that it is competitively priced to go against the GTX 1070 which originally retailed for $449. If these numbers are true than we are easily looking at one of the performance per $ leaders of this generation. Just like the R9 290 and the Fury, it looks like AMD has reserved the value sweet spot for the second most powerful GPU in its lineup
The Radeon RX Vega 64 will be powered by dual 8 pin connectors and takes two slots worth of space. Display outputs include a single HDMI and triple DisplayPort connectors. On the back of AMD’s flagship graphics card, we can see the GPU Tachometer switches and LEDs. These tell the load of the GPU itself while the switches let you control the colors (Blue or Red) or disable the LEDs all together. The card is about the same length as the GeForce GTX Titan X and Titan Xp.
The graphics chip will be utilizing the latest 14nm GFX9 core architecture which is based on the NCU (Next Compute Engine) design and measures approximately 484mm2. The Vega 10 graphics core deploys 12.5 billion transistors. The graphics chip will feature 64 Compute Units or 4096 stream processors and 256 TMUs. AMD plans on increasing the throughput of the chip through increased clock speeds. This will allow AMD to pump numbers better than the Fiji GPU which is based on the 28nm GCN 3.0 architecture and comes with the same number of cores, 4096 SPs.
