HD 7790 and 650 Ti BOOST Roundup: Asus, MSI, and Galaxy

Author: Josh Walrath
Manufacturer: PC Perspective

Results: Luxmark 2.0

I was quite curious about the OpenCL performance of these latest cards.  AMD has really been pushing OpenCL as of late, especially in advance of the release of the Kaveri APUs.  They have a pretty solid OpenCL 1.2 implementation for their GCN based chips.  NVIDIA of course has been blowing the GPGPU horn as loudly as possible over the years and focused on CUDA.  Oddly enough, Kepler made compute performance take a back seat to enable better performance and efficiency in graphics applications.  I used the 64 bit version of Luxmark 2.0 with the Sala test.

I used this test on just the 3770K and not just the video cards.  Some really, really interesting results here.  The 7790s had outstanding performance in this benchmark.  The 650 Ti BOOST?  Not so much.  In fact, we can almost categorize this as the ViRGE 3D of OpenCL software.  It acts as a decelerator when used with a high end CPU for this particular workload.

You forgot to mention how to do the ole' pencil mod to enable that extra SMX unit in the 650 Boost :)

GTX Got the 650 Ti Boost. Not sure I understand everything about it but it is a huge improvement over the 260 that came in the computer. On the other hand this is a dell 30 inch monitor...Kind of thinking a GTX 770 might offer a little more umph.

Yeah, a GTX 770 is somewhat of a must anymore for modern games and a 30" 2560x1600 monitor.  The 650 Ti BOOST could push the pixels, but in games like Metro it (and the others) choked.

As a side note I'm still amazed at how well a 5870 holds up considering it's age.

It really was a great card.

It also costed a whole lot more back in the day than either 7790 or 650Ti BOOST.

Yes, it did.  But consider that if you had bought it new at $400, that is a pretty good investment going on 4 years and still very useable.

I have had a 5850 1GB for 3 years and it works well for 1080p gaming.
Bought it for Dirt 2 mostly as it was one of the first DX 11 games I think.

DiRT 2 was one of the first DX11 games.  I remember watching the first footage they released during QuakeCon that year.  Was really impressed... it sorta inspired me to get back into racing games.

The 7790 models you tried, are both 2 GB?

July 5, 2013 | 02:32 PM - Posted by Josh Walrath

Both are 1 GB models.

How did the galaxy not win this with the better average benchmarks for games and others?
