AMD Readying Radeon HD 6790 for April 5?

By - Source: Tom's Hardware US | B 47 comments

A combatant for the Nvidia GeForce GTX 550 Ti?

Nordic Hardware has a report stating that AMD will be launching a new mid-range graphics part called the Radeon HD 6790, which is supposed to be an answer to Nvidia's just announced GeForce GTX 550 Ti.

The Radeon HD 6790 will be more powerful than a Radeon HD 5770, at a lower price than Radeon HD 6850. According to the report, the 6790 will use a GPU called the Barts LE, which uses AMD's classic VLIW5 architecture with 10 SM units with 800 stream processors. In comparison, the 6850's Barts Pro GPU has 12 SM units and 960 stream processors.

The clock speed is said to be at 840MHz and the memory at 1050MHz (4200MHz effective), all on a 256-bit interface.

ND said that this new card was supposed to launch on March 31, but instead is now launching on April 5.

    So im now wondering how thats going to work? If its going to perform between the 5770 and 6850 but be priced below the 6850 but presumably above the 5770 then here in the UK it has a £30 price gap to fill.
    Surely AMD are not at last going to drop the 5770 to where it should have been priced all along is it?

    The 6670 looks to be the fastest card that doesn't need the use of a 6- or 8-pin connector, however only barely - the 4670 may be old but I expect both cards to compete. The 4670 has a slight clock speed deficit, only half the potential bandwidth and two thirds of the shader power, but is superior at texture fillrate. Will that matter in the end? You're unlikely to play in higher resolutions on either card really so perhaps it won't, and the lack of DirectX 11 is hardly an issue.

    I'd really like to see such a card with 4770/4830 class performance. I'm surprised we've not had one already.

    The 6790 is an interesting prospect... maybe it's time for the 5770 to bow out.

    You are on crack dude, the 5770 has been dirt cheap for the longest time now. It can be had for $100 on newegg, which is a great price for that card. Shell out another $100 for xfire 5770's and you have Dx11 performance on the level of a 5870. Not too shabby for $200.

    with the 5870's down to about $220, you get guaranteed performance(even on games that do not scale with Xfire) for just over the price of 2 5770's now. Clearly if you have one 5770 its the way to go, but if not, I would bet on the 5870(or better) for sure.

    I've checked out that article and I'm a bit concerned now. Let's not have another 5830, please!

    It may have made more sense to offer a 6850 with a 128-bit bus; increasing clocks to compensate for the disabled SM units might alleviate some of the performance drop but increasing power over a more powerful model is a no-no.

    £ isn't the same as $. For what its capable of compared to the competition its always been over priced. At release it was too close to the 4870 which was cheaper and after the 460 was released its been a totally irrelevant card full stop.

    Maybe i will sell my 4870 used and replace it with this card in my living room pc. A low power, 4870 level card that is the power/heat/size of a 4670 would be a good thing for a htpc.

    That's a little like wishful thinking if you're talking about the 6790 as it stands to use about double the power of a 4670.

    I was hoping the 2 x 6-pin was a typo but the 6790 is slated to have a TDP of 150 Watts just like 6870.

    How did AMD make something less powerful than the 6850 but require significantly more power?

    That would at a guess probably be bad silicone requiring more voltage to keep it stable. Basically selling off chips that didn't make the grade for 6850's
    Nothing both camps haven't been doing for years.

    You are beyond wrong. The 5770 has always been a relevant card, before and after the 460 release.

    The 4870 didn't support Dx11, and it much larger, hotter, and consumed much more power. Not to mention the 5770's scaled much nicer in crossfire, going toe-to-toe with crossfire 4870's despite being smaller, cooler, and consuming less power.

    When the 460 was released, it no was undoubtedly faster. But you had to pay for that performance, as it was $50-60 more than a 5770. When 460's released they went for $220-230, while the 5770's were around the $160-170 mark. Ever since the 5770's price has steadily dropped, all the way to $100 now, offering awesome performance for an affordable price.

    The 460's price has dropped too, but a 1gb version is still going to cost you at least $170. Spend $200 and you can crossfire 5770's, which destroy a single 460 for only $30 more.

    Now please prove to me how the 5770 is irrelevant? (or ever was for that matter)

    Why AMD are you naming this coming product the 6790? Why not the 6830? I think it would make more sense that way because it is using a Barts GPU like the 6800 Series is using. Or would that make too much sense?

    Hehe how many missunderstandings are possible in one wall post!? LOL - The guy you are responding to is in the UK! In the UK the prices are different from the US full stop. Here the 5770 is about £100 ($150) - about £5-£10 cheaper than the 460 768 at best. Sometimes its even more expernsive than the 460.

    So its not that the 5770 is irrelevant as much as it is that your comment is irrelevant because prices in the US are completely different.
    Cheers

    If I were to upgrade every time a new generation of cards comes out I would be wasting money, I still have a HD4670 and couldn't justify getting a HD5000 series, but skipping a gen onto the HD6000 seemed to much of a price jump as they were all high end.

    So to have a card that squarely addresses the mid-range and gives out such good performance is definately a tempter, especially if the price is aggressive matched to beat the nVidia offerings.
