Nope, they're Nvidia, we're still wating to see benchmarks for these RDNA 2 architectures, also factoring the custom silicon as well. Even still, the TI doesn't seem to blow the S that much out the water to justify the upgrade, the S is a solid card.
RTX 2080 SUPER vs RTX 2080 Ti Game Performance Benchmarks (i7-8700K vs i7-8700K) - GPUCheck United States / USA
RTX 2080 SUPER versus RTX 2080 Ti performance comparison. Compare graphics card gaming performance in 48 games and in 1080p, 1440p, and 4K at Ultra, High, Medium, and Low quality settings. Compare specifications, price, power, temperature, and CPU bottlenecks.
If you decide you want to compare Radeon 7 to Vega 64 then fine, R7 is faster with fewer shaders but it has 210% memory bandwidth, a 113% clockspeed and has 93.75% of the shaders Vs Vega64.
PS5 otoh has 80% memory bandwidth (peak), 122% clockspeed (peak) but only 69% of the shaders. We also don't know the top count of either console.
PS5 is not going to deliver better graphics or smoother framerates than Xbox SX. It will be close, it will still look really good but it will be a little bit behind because it has a slower CPU and a slightly weaker GPU.
PS5 will probably sell more though.
