Arrow ** ATI RADEON 7950 OVERCLOCKING & HEAVEN RESULTS!! **

Hi there

First things first, this is all the benchmarks you are getting, so be grateful for this. I've done this to simply see how they clock and how the Heaven scores compete to the NVIDIA GTX 580 3GB and ATI 7970 3GB.

First of all the card tested is a stock version from one of the AIB's, the cooler is rather cut down and not that powerful, as the same AIB also has OC editions which come with a much better cooler. However even still with this stock average performing cooler the card managed the following:-

1. Using ATI OverDrive it maxed out - NDAMHz Core & NDAMHz memory.
2. Using Asus 7970 BIOS it managed - NDAMHz Core & NDAMHz memory.

Flashing the card was the same as flashing a 7970, very easy, unfortunately it DID NOT unlock any additional shaders, the card had the stock 1792 shaders still, though these cards do have a FULL 32 ROPS.

First of all here is the results of this card:-


ATI RADEON 7950 Stock (NDAMHz Core / NDAMHz Memory)




ATI RADEON 7950 Maxed on Overdrive (NDAMHz Core / NDAMHz Memory)




ATI RADEON 7950 Maxed OC on Asus OC BIOS (NDAMHz Core / NDAMHz Memory)


1680x1050 Resolution with 4x as per OcUK Benchmark


1920x1080 Resolution with 4x as per OcUK Benchmark


2560x1600 Resolution with 4x as per OcUK Benchmark




Heaven 2.5 @ 1920x1080 & 2560x1600 with 4x and 4x enabled for testing on NVIDIA GTX 580 3GB OC @ 902MHz Core & 4355MHz RAM








ATI 7970 Results at Max OC using Asus BIOS - 1225MHz Core & 7800MHz RAM:-











Conclusion

A very impressive card indeed, with a price point in the region 350 Inc. VAT that matches GTX 580 1.5GB pricing and this card matches one for performance but has two bonuses. More memory which makes it more future proof and better for high-res gaming, but even more importantly just like the 7970 these cards are hugely overclockable.

Clocking the 7950 at NDAMHz core and NDAMHz memory which they all do with ease (with the Asus BIOS), you have a stock 7970 performing card for considerably less money. Unfortunately it does seem like its not possible to unlock the shaders and as we've seen the 7970 is a true overclocking demond.

So in essence the maximum stable overclock I achieved was NDAMHz Core and NDAMHz memory using the Asus BIOS. Using that same BIOS on a 7970 were talking around 1225-1255MHz Core and 7500-7800Mhz memory. Though remember the 7970 has the full 2048 shaders which gives a decent performance boost.

All in all the 7950 is approx 30% cheaper than the 7970 but when flashed and overclocked its only about 10-15% slower. The 7970 is faster and definetely has a better cooler without doubt, plus a more quieter cooler too, that really helps to keep the case temperatures down, wheras 7950 coolers just heat your case up. So it still stands if you want the best buy the 7970.

Overall the 7950 is great value for money, against an overclocked GTX 580 3GB the 7950 when overclocked is faster in benchmarks and its overclocked game performance should be at least on par with an overclocked GTX 580 3GB gaming performance, so as the card cost less than a 580 3GB, the 7950 is good value.

We have stock now and for launch on January 31st we shall approx 500 cards.

UPDATE:

Just discovered it maybe possible all 2048 shaders have unlocked, just GPU-Z is reporting wrong.

Card is running a 7970 BIOS fine though, am going to do more testing.

Very impressive, I was deciding on a 6950 but I may wait for this as its only 90 more. I have yet to read into the performance difference from the 6950 to the 7950. Is it worth the 90?

Its more than 90 more! We sell 6950's at like 210, I said these will be around 350, thats 140 from my maths.

Quickest way to test Gibbo
Run a 7970 bench at 950MHZ on the core, then run the flashed 7950 at 950MHZ on the same settings.
Compare both results.
Would certainly be interesting.

Nice work Gibbo- good luck with it and keep us posted.

The results look really good for the 7950 and being the same price as the 580 1.5gb it should be a no brainer.

Is this another little gem from AMD?

Stock 7970 performace from an overclocked 7950 at that price point is stunning, if they can be unlocked to 7970 then they're simply amazing and will sell like hot cakes on a cold winter day!

Well I've just re-ran Heaven at 810Mhz Core & 5000Mhz Memory with the 7970 BIOS and score was 1381, so no difference unless your counting the 2 points.

From that I'd say were still on 1792 shader, but maybe Heaven is no use for that?

I shall bench at 7970 speeds, take result, then put a real 7970 in and bench to confirm for sure, but won't be until tomorrow now.

Nah because I'm not one who likes to faff around to make a diamond out of a piece of glass tbh.

I've never overclocked my CPU. I don't buy things based on what you can turn them into, I buy things based on their performance out of the box.

You wouldn't like me really, I'm pretty much anti overclocking

In a way I would kinda agree but the 7970 especially seems to be designed to be underclocked so crank that baby up!!

Can we expect MSI to market this as the 7950 Glitter Edition?

I take it that these will crossfire without problem with the 7970 ?

Yeah I did got 1ghz on shakey drivers. It's AB that makes it unstable, but I must have a fan profile.. I worry otherwise lol.

I dunno man.. I was just born in an era where you got nothing for nothing and didn't expect to.

Plus I don't like taking risks based on "What if". So basically I would never buy a card based on what I may be able to do with it, because if it didn't work out then you have bought something you didn't really want.

Yeah, but it'll cost you !

How much?

Pound..

With the GK104 being linked with a $299 price, you can imagine where pricing for these will be in a month or two(sorry Gibbo). AMD are fully taking advantage of no competition we can do what we like pricing.

So its 33% faster than a 580gtx overclocked by 15%(if I'm remembering the 580gtx stock clock right?) making it basically 45% faster than a stock 580gtx..... and with what I assume will be some nice "unlocked" bioses for higher overclocking(judging from 7970 results) with another potential 10% overclock just on air to add on top of that make these awesome cards.

If they unlock shader wise as well you've got an epic card. But pricing will likely be in the range of $350 within a month, maybe 2. Depends, you need a card priced around/below previous gen to cause the price drops everyone has been waiting for and AMD cleverly(irritatingly also) are seemingly holding back the 7950 and probably the 7870 as long as they can to get as high a price on these as possible

Once prices adjust these cards will be awesome.

YOu have to laugh at people who can't work out the true potential of these cards, the not even top end card is 45% faster than a stock 580gtx..... but the 7970 isn't really any faster than a 580gtx according to some

Hmmm due a lump sum of cash inside the next few weeks, its either a pair of these and constant ear ache from the missus or a deposit on a new bathroom and slightly less ear ache

So this pretty much makes the 580 redundant then?

No Advertising?

Can I reserve one?!?!

If it's definitely around 350 then I'm definitely buying one!

No they are not. What they are doing is looking at Nvidia's "Fat and greedy" prices, comparing their cards in spec and performance and then pricing them accordingly.

How much is a 3gb 580? Oh yeah ! 430.

How much is a 1.5gb 580 that the 7950 will take on? Oh yeah ! 350.

AMD are taking the pee because Nvidia have taken the pee for ages. FFS, how can you charge frigging launch prices nearly a year after launch?

Quite easy if you're a fat bugger greedy corporation like Nvidia.

So right now AMD cards are the value cards, as crazy as it sounds.

Hi there

Right some odd Heaven results here:-

7950 @ 925MHz / 5500MHz = 1504 points
7950 on 7970 BIOS @ 925MHz / 5500MHz = 1545 points
7970 @ Stock (925/5500) = 1584 points

So even though according to GPU-Z the shaders are not unlocking, flashing to the Asus 7970 BIOS is definetely giving a performance boost, though its not quite at genuine 7970 performance levels, kind of like half way from the results.

So either some shaders are unlocking or the 7970 BIOS is making other improvements, maybe memory timings etc. which is giving the boost.

Still flashing the BIOS is so easy anyway and it would appear the 7970 BIOS is giving some performance enhancement even when clock speeds are identical.

Are you checking on the latest GPUz?
GPUz 0.5.8

It's optimised for 79** cards and now shows original clocks and oc clocks

It's still worth that, that's why.

When AMD get a range out that beats Nvidia like for like Nvidia will drop their prices. That will then force AMD to do the same on lower end parts.

Due to Nvidia having a commanding lead they haven't dropped prices of the 500 series. And given that the AMD range was always cheaper any way they haven't had to either.

Price to performance the 6970 is one of the cheapest cards on the market. And if what you say is right (not doubting you, I just paid no attention to the 69xx prices on launch because I wasn't looking for a new card) then they were very cheap at launch also.

But alas, this is what happens when one product has a commanding lead. See also - Sandybridge. That won't drop any time soon either, and given that AMD don't even have a paper launch or any exaggerated charts Ivybridge is a "free launch" and thus will come at a price.

The last time GPUs dropped like stones in value was when the 5000 series launched. Then the Fermi came, but were a bit of a fail, meaning Nvidia couldn't price them as they wanted to. They fixed that, 5000 series cards dropped like the proverbial lead balloons and so did the 4 series.

I mean FFS, four months after the 470 launched at 350 I got one for 179.99 delivered.

Just checked with that, still showing 1792 shaders.

So it would appear the 7970 gives a performance boost but is not unlocking the shaders or at least according to GPU-Z.

Will definitely be interesting to test them on games, Crysis the original would be perfect as it seems to scale with shaders quite well.
