[SOLVED] Radeon 5700xt vs Radeon vii

[Anthony Bennicelli]

I am in the process of re-configuring/upgrading my 900d watercooling rig. I plan on watercooling either card with an EK waterblock. I still game on Eyefinity(5760x1080 144hz 1ms). I know with larger resolutions, more vram is appreciated. Would the extra cost for the vii and possible over clock be worth it?

I understand that the Radeon vii has been discontinued, but I can currently still get the Powercolor vii for under $700.

Nope, not worth the money compared to a ~$400 5700 XT. The VII gets single digit % better performance, for ~70% higher cost.

I agree, in front of the 5700 XT GPU, the price/perf ratio of Radeon VII has been very poor. Just buy the new NAVI GPU. If you main goal is to play games, then there is not point in getting the R7 GPU variant.

This R7 wasn't meant to be an actual gaming card to begin with, because AMD had plans to target the compute/HPC segment as well. They didn't have much choice either, so they just made some changes to the existing GCN architecture on a refined process Node though, giving us this R7 GPU.

The Radeon VII wasn't a very worthy contender. It looks like AMD really wanted to compete with NVidia's RTX 2080, but didn't have much choice apart from re-branding and releasing a cut-down variant of their current MI50 Instinct compute card. Seems like a desperate move from AMD.

This is also evident from the FP64 performance of this R7 GPU, which sits around (3.5 TFLOPs). AMD had a change of heart, deciding that their Radeon VII users deserved a little more FP64 performance from their new gaming flagship, making the GPU more appealing to professional users as well, while maintaining the performance advantages of their Radeon Instinct lineup.

But for gaming FP64 is irrelevant though. The inclusion of 4 existing HBM2 memory stacks also actually made this card to be priced in a higher bracket, as compared to the Vega 64 and similar cards.

That's the reason this product has been discontinued by AMD, due to the cost involved as well.
