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.
Well, it is nice to see that this application can utilize more than a single card at once! AMD did a nice job with their GCN architecture. It was a big shot in the arm for AMD when it came to GPGPU workloads. NVIDIA again cut down the GPGPU abilities of their Kepler products, except for the GTX TITAN as well as their professional level cards based on GK110. So in this instance, the GTX 770 and 760 are not that much faster than the i7 3770K.
Looks like very solid cards.
Looks like very solid cards. I really want to see some custom cooled versions of the 290 soon.

Shame you started using DDOF
Shame you started using DDOF in Bioshock Ryan. The game looks so much better with it disabled, not to mention the impact it has on performance numbers.
Well, those numbers are worst
Well, those numbers are worst case scenarios for extreme graphics. Happily, as a user, you can disable it and get a performance boost with your setup!

I’m kind of curious as to why I can find 270 boards with 4GB and 280s seem stuck at 3GB.
The 270s use a 256 bit bus,
The 270s use a 256 bit bus, so they can cram 4 GB of memory on them. The 280 has a 384 bit bus, so to go above 3 GB they need to use 6 GB. That is much more expensive than they feel that most users will go for, so they keep them at 3 GB. Plus, the 280s are already overpriced with just 3 GB right now! Someone really didn't figure out this demand thing…
great review Josh. After
great review Josh. After reading this, I’m convinced that miners are responsible for every known world problem. I mean all of them, including excessive cow flatulence!
They have ruined my upgrade plans for the time being. :/
thanks for the review.
Damn those miners! At least
Damn those miners! At least you can get the R9 270x at a decent price… but yeah, no 280X anywhere near the promised $299.
Is it me or are the graph
Is it me or are the graph numbers switched like the min FPS To high and the avg FPS to low on the Unigine Heaven benchmarks.
LOL, yup! Obviously I
LOL, yup! Obviously I transposed the numbers. Just pretend Min is Avg. and Avg. is Min!
I bought a Gigabyte Windforce
I bought a Gigabyte Windforce R9 270X last November. Having upgraded from an MSI GTX460 with only 768MB of video memory, the 270X was a fantastic deal!
The GTX760 might be the performance equivalent for the 270X, but the price point is mush closer to the older GTX660 here in Japan. Video cards are priced fairly higher than the US. nVidia cards in particular are pricey. When I bought my car a MSI TwinFrozer GTX660 was going for around $200, while the Gigabyte Windforce 270X was only slightly more at $225. Most of the GTX760s that I saw were going for around $370 to $400.
Yeah, that’s a pretty steep
Yeah, that's a pretty steep increase in price as compared to performance on the R9 270X. The 270X is still probably the best overall deal in the market for what you get.
Makes me glad I got the HD
Makes me glad I got the HD 7870 for $120 after rebate over a month ago. Not sure if I can bring myself to get the 270X at current prices.
Glad I was able to grab the
Glad I was able to grab the Asus R9 280x DC2T for my new build before the rush. Snuck it out of Newegg beginning of December for $319…before the gouging began.
Love it.
It certainly is a nice card.
It certainly is a nice card. Good job on grabbing it before the insanity hit.
Notice the dif in the fans on
Notice the dif in the fans on the 280X other than the actual card size and such…. Put that on the cooling on the 270X and you could no doubt O.C. more. Gotsa LOVE ASUS….!!!! I do.
hello everybody, sorry for my
hello everybody, sorry for my english i am french
i have a lot of problem with asus r9 280x directcu 2 top artifact game freeze and stop and return in windows and i dont understand why if someone know about please tell me
