Analyse This: The Relative Efficiency of Nvidia Architectures...

 

For the last year, I've been looking at the predicted performance and efficiency of the RDNA architecture(s) as those were what I was most familiar with and most interested in due to their presence in the now current gen consoles. I determined early on that there was no IPC improvement between RDNA 1 and 2 and that it was merely* a clockspeed bump that was dictating any performance increase per compute unit (CU). However, in the back of my mind I was asking myself how Nvidia's architectures stack up against one another in a similar comparison but I knew that you can't normally directly compare between architectural designs except when the comparison is abstracted via different metrics. 
*I say "merely" but I still think it's impressive how far AMD were able to push the working frequency of their chips.
Luckily for me, this is exactly what I did for the final RDNA analysis - I used real world benchmarks  in games and actively used frequency (performed by TechPowerUp) to inform the relationship between performance and architectural aspects. While I wasn't able to pull as much information due to the differences in architecture, I was still able to compare and contrast between AMD's and Nvidia's respective approaches to graphics card design and I'll try and take a look into the future to see what we might expect next, as I always do...

DirectStorage and its impact on PC gaming...


At the beginning of the year, I railed against the focus on standardising game API features across PC and console, specifically with regards to designing systems around the limitations of the console hardware. Well, today we got some updated information on how DirectStorage will work and it's basically as bad as I said it would be...
