So let me try another wrinkle: How does a 3090 stack up against modern workstations on the usual measures of performance/price, such as SPECmarks/$? My guess would be that the large backwards compatibility comes at a price. Also, how much slower and/or more expensive is the 3090 as a result of maintaining such backwards compatibility? (I realize that might be hard to get a handle on.) -- Dan Mocsny Internet: dmocsny@minerva.che.uc.edu
