Radeon R9 280X Can Be Paired with Radeon HD 7970 Cards

By - Source: Image via HardwareCanucks | B 37 comments

There are some advantages to new hardware that very closely resembles older hardware.

AMD just announced its new R9 280X earlier this week, so it's unlikely you've gotten your hands on one of these cards just yet, but when you do, you might like to know that this card is compatible with AMD's Radeon HD 7900 series in CrossFire. As our own Chris Angelini reported in his review, the cards will work in tandem if choose to go that route:

 

"To answer whether existing Radeon HD 7970 cards can be paired with the new R9 280X, yes, they work together," Chris writes. "A quick Fraps-based test showed one 280X hitting 52.9 FPS in Battlefield 3 at 2560x1440. Dropping a 7970 GHz Edition next to the newer board pushed frame rates to 102.3 FPS. When it wasn't in use, the 7970 properly spun down according to AMD's ZeroCore technology."

In case you missed it when these cards, launched, the R9 280X’s specs are very similar to the Radeon HD 7970 Ghz Edition. The Tahiti GPU in the R9 280X features the same 2048:128:32 configuration, and packs a 384-bit memory bus rocking 3 GB of GDDR5 (which AMD says should operate at 6 GT/s). The one notable difference is the "new" card's engine clock, which tops out at 1 GHz. Other than that, these cards are a great match.

The folks at HardwareCanucks came to the same conclusion and provide visual proof in the form of the screen cap featured above.

    This was already mentioned in the review. Jane, do you just regurgitate the information that is already posted on this site?

    Reading comprehension is so difficult for some and apparently the rest can't seem to be bothered to read the article in its entirety :pt1cable: .

    This is indeed sweet, good job AMD, keep up the good work. And have you guys seen the R9 280X Toxic? http://www.anandtech.com/show/7406/the-sapphire-r9-280x-toxic-review

    Considering that its the same GPU, I don't think AMD did much.

    Its a nice feature but still I think what everyone wants is a real review of the actual new hardware. I know I do. Along with a price please.

    And that Toxic is nothing to really look at:

    That was a Toxic edition. 6GB VRAM and the ability to boost to 1200MHz. It also used the much better Vapor-X design (check a Vapor-X vs Dual-X Sapphire GPU and the Vapor-X can clock higher and runs cooler).

    Sweet runing an 7770 on 1366x768 with no desire to go above 1080p, i think i will get a HD 7950 in november and then a 280X next year when the price comes down.

    that way i will get the best of both worlds (mature drivers for the 7950 new tech for the 280x)

    So AMD releasing the same tech under a new label is okay, but Nvidia gets flamed for it?

    Try running the GTX 680 and GTX 770 in SLI...

    Two year old. Four years ago there was the HD5870 which was VLIW5 technology.

    Honestly you are probably bottlenecking that GPU. And for now 1080 is fine. But soon 1080 will become a bottleneck and there will be better resolutions for less that GPUs can handle.

    But the 7770 can run most games decently at 1080.

    A quick Bios flash and off you go!

    bios flash shouldn't be necessary FYI

    and i don't understand why they got heat for it. did they not drop the price? isn't it good to see high end cards becoming mid-end year after year? or do they expect a 300000% increase in performance from on lifetime to the next? have some real expectations people. there is nothign wrong with rebranding, as long as there is some benefit to it

    Can it be done without a BIOS flash?

    BIOS flash = void warranty = SO NO. AMD is better, because they work out from box.

    In my country you would only have 12 months warranty so if it's an old 670 then it wouldn't matter would it?
