ATI Radeon 4790

[SickBeast]

There's nothing in that report about the price. How can people bash (or praise) this card without knowing how much it will cost? IMO you can really tell where people's loyalties lie in this thread, on both sides.

I have no opinion on this card until we know how much it will cost. I have a feeling that it will overclock to 4890 speeds, but will be hindered in future games by its 512mb.

Well...if it performs between a 4850 and a 4870 (which I think the article hinted at) then it stands to reason it would be priced in between the two.

Holy shit, SickBeast is the voice of reason in a thread that is turning into fanboi v fanboi?

I have seen it all. :beer:


And although Wreckage did not properly articulate the point, it is still valid.

You can search through these forums and see the ATi squad bashing nV for the 250 and the rediculous naming scheme of GT200. He was merely trying to point out the hypocracy, although it could have been done better.

But lets not discuss individuals, because that is against ToS. Lets discuss the topic.

These could be really good for cheap..........

Excellent observation, and I think that tells you just how many 4890's ATI is planning on slamming out .

As far as the actual card goes, it seems like you're pretty much getting a 4850 with 102GB/s of bandwidth. Hopefully, the PCB will retain a lot of the features of the 4890 (like software voltage adjustment). My guess is MSRP at launch will be $120-130ish (if the 4870 512MB stays at $150). Time will tell how much of an overclocking beast this card is; but, if they end up hitting 800MHz, ATI will have another budget bang-for-your-buck winner.

Kinda sucks that every new card planned puts my 4830 to shame..

I liked this card too..

That's worse than a rebadge. :shocked:

Remember the old days when both Nvidia and ATI only had one model,you should know nowadays both sides are just as guilty and flood the market with choices.

End of the day you can argue more choice is good,also its not like you are forced to buy a card.
My opinion on the 4790 card is neutral at this time, as SickBeast said no pricing yet,however its another choice for those that might be interested in buying it.

Yup I think so too. AMD was having some issues with 55nm.

and if it oc's like crazy and are mad cheap? Let's wait and see some tests by the major sites.

I dont think AMD/TSMC is having any sort of issues with 55nm at this point in time (although not saying yields are at 100% either ). I think its rather to do with the fact that there isnt any other SKU apart from the HD4890 that uses RV790 core. This results in alot of usable cores (for other market segments) go to waste.

So I think AMD is looking out to make some money here with the HD4890 rejects. Which isnt a bad thing after all depending on prices of course.

So which would be stronger - 4870 or 4790?

And when, oh when, will ATi cards be able to fold on par with nVidia's parts? Absolutely love the $/perf of ATi cards - but not willing to give up my F@H ppd...

From the specs my guess is the 4870 would be faster, 750MHz core vs. 600Mhz. But with overclocking, who knows. The 4870 is good for 10% generally this card coud be better or worse, not known yet.

 

[Candymancan21]

The card only has 512mb, depend how you play games 512mb could be a big hinderance.

 

[nemesismk2]

The ATI Radeon 4790 sounds good, lets hope AMD can get them into stores unlike the 4770 which is always out of stock!

 

[BFG10K]

I think this is a way for ATi to get rid of their excess cores before DX11 parts arrive.

Since when?

There's also another 47xx series card the HD4730, it's a "RV770LE" core @700MHz, 55nm, 640 shader units, 128bit memory + GDDR5. Link.

I wonder where they will squeeze those cards... Not to mention right now a slower HD4770 is more expensive than a HD4850! The latter can be had for ~90$... The 40nm card is >100$. So this HD4790 card will be what? Faster than a HD4770, faster than a HD4850 and cost...?

Not to mention the HD4730... It's slower than the HD4770 from the specs. But faster than a HD4830.

I mean, I'm getting a bit lost...

 

[OCGuy]

Bring on GT300 and 5XXX already....

2 theoretical TFLOPs ftw

 

[happy medium]

Seems to me they just improved on performance of there 3 bottom end cards to edge out Nvidea in price, performance, and power consumption.

HD4730 vs 9600gt
HD4770 vs 9800gt
HD4790 vs gts250/9800gtx+

If the prices are in line I see 3 wins for ATI/AMD.

 

[Rezist]

It almost looks like AMD is going to phase out the 4830/50/70, so they need some replacements. I'm surprised at how fast they are adopting GDDR5 across the board as well.

There's probably no reason to continue with the 4830/50/70 if the other core can be made for a similar cost.

 

[bunnyfubbles]

While I'm overall pleased we're continuing to see this onslaught of excellent price/performance parts from AMD, I'm finally upset with the naming scheme. While I think people made too much of a fuss with the 4770 - the 4700s in general made sense, as did the 4800s, each retaining a general common core and even memory interface (ie 4700 = 128bit, 4800 = 256bit) - this one truly pushes things out of whack, it should clearly be named a 4860. This is the worst fudging up of a good naming scheme since ATI repackaged the Radeon 8500 as Radeon 9000-9250 (before then Radeon 7xxx = DX7, R8xxx = DX8, R9xxx = DX9, etc)

I guess you missed this part:

Price-wise, it is expected to sit between the HD 4850 and HD 4870.

Precisely. If these 4790s aren't true rejects or cripples (or at least not all of them) then they should theoretically be able to overclock to 4890 speeds (ie 850MHz+). Of course you'd most likely have to overclock them with a 3rd party tool.

Another thing holding back the 4790 is 512MB of memory whereas there are 1GB 4870s
