Radeon vii outperforms titan v with 100mh / s mining performance
Table of contents:
AMD appears to have reclaimed the Ethereum mining performance crown from its latest Radeon VII graphics card. This Vega-based graphics card manages to outperform Polaris, Fiji, Titan V and Turing at the same time, but will it make mining profitable again? That is difficult to answer.
Radeon VII achieves 100MH / s throughput in cryptocurrency mining
Radeon VII manages to achieve a whopping 90MH / s, nearly triple the performance of an RX Vega 64, 29% faster than the Radeon Pro Duo, and outperforms the Titan V by a large margin. RX Vega 64 lags well behind the Radeon Pro Duo, and the Pro Duo lags slightly behind the Titan V in terms of raw hash rate in stock configurations.

After adjusting the Radeon VII, it is possible to achieve a hash rate between 90MH / s and 100MH / s. According to VoskCoin on BitcoinTalk , the following setting brings 91MH / s to 251 watts. This configuration provides a 21% efficiency improvement over the 319 watt power consumption in stock.
| GPU | Stock MH / s | OPTIMIZED MH / s |
|---|---|---|
| Radeon VII | 90 | ~ 100 |
| Titan V | 69 | 82 |
| Radeon Pro Duo (Fiji) | 64 | |
| RX Vega 64 | 32 | 44 |
Compared to Titan V, Radeon VII is a much more compelling option. The AMD graphics card is vastly cheaper, costing between $ 680 and $ 700, while the Titan V is in the $ 3, 000 range.
Compared to the Polaris architecture, Radeon VII is a more efficient option. The Radeon VII consumes less power than three RX 570s / 580s and occupies a single PCIe slot instead of three, allowing for higher performance density on mining rigs and lower heat output.
The increased hash rate of the Radeon VII is largely due to its memory bandwidth compared to Vega 10. The RX Vega 64 has a memory bandwidth of 484 GB / s and 8 GB of HBM2, while the Radeon VII has a memory bandwidth of 1 TB / s and 16 GB HBM2. RX Vega 64 has a TDP of 295W, compared to the Radeon VII which is 300W, which makes the latter a much more efficient card with the same power consumption.
