Hello you fine Internet folks,

Today's article is on Intel's Battlemage Architecture found in the B580 dGPU and what improvements have been made compared to the last generation Alchemist architecture.

Hope y'all enjoy!

This is a Most Excellent essay to watch, that explores sooo many worthy topics and is relevant for everyone!

Just don't start watching it right as you were about to go to bed, as I did, lest you want to inevitably extend your wake up time to the full length of the video.

Very cool "simple" shader optimization Thread :) Interesting to see how fare you can get when taking into account GPU execution models into account !
Let's wrap up this lovely week with a nice technical post

This is the "case study" from my Masterclass at GPC, where I apply a series of optimizations to improve the effective bandwidth of a 3x3x3 blur (a proxy for a huge set of operations on volumetric data)
