Radeon RX Vega 64 vs 580 |
Released August 7, 2017
AMD Radeon RX Vega 64
- 1.2 GHz
- 8 GB
by www.tweaktown.com (May, 2017)HBM2 is the memory technology that will be used on Radeon RX Vega, offering some great bandwidth numbers of up to 512GB/sec - but it'll be the memory footprint that makes the difference.

Released April, 2017
AMD Radeon RX 580
- 1.3 GHz
- 8 GB GDDR5
by www.tweaktown.com (Aug, 2017)So, if you have 16GB of RAM you could dedicate 4-6GB of it, so it would - in a way - combine with the 8GB of HBM2 for up to 14GB of VRAM.
