Hi all. After receiving my Powercolor HD7970 at 9:30 yesterday morning I decided to work a half day and get some BF3 Eyefinity benchmarks done and write a "brief" review putting across my opinion on the card and how it compares to my "old" HD6970. First things first, we all know the architectural changes that have happened between the HD6970 and this card (move from VLIW4 to GCN), therefore I won't bore you with going into the details here. The likes of Anandtech and Bit themselves can do a much better job in this area. Anyway, onto the card itself. The HD7970 I ended up going for is a Powercolor model which I managed, by a stroke of luck, to get for under £420 from Ebuyer. The same card is still available for £444 if anyone does want one for a decent price. Considering all of the cards are reference design and basically the same, I didn't see the point in spending more for the same card with a difference sticker on it. The card itself is literally the reference design with a sticker on the fan itself. There isn't much more to say in this area as in the end it looks like every other HD7970 for sale bar the XFX DD model. Size wise it is basically identical to a HD6950/HD6970 reference card. It measures just under 11" nose to tip. Connectivity consists of a single DVI port backed up by a single HDMI port and 2 mini DP connections. The mini DP connections can be connected to a hub to provide more connections for Eyefinity if you so wish. In the box you get the normal user guide and driver CD (Very useful in my case as the 12.1 drivers I downloaded didn't work... :grr. You also get the following: - Crossfire bridge - DVI-VGA adaptor - 6 pin to 8 pin PCI-e adaptor - HDMI to DVI adaptor - Active mini DP to DVI adaptor - Mini DP to DP cable Basically you have the ability to run Eyefinity right out of the box assuming you run 3 DVI equipped monitors. Considering the active adaptors still cost £15+ this is a pretty good bundle and not doubt goes some way in explaining the relatively high ticket price of the card itself. You also get a voucher for a copy of Dirt 3, great if you don't already have the game (like me). Interestingly the voucher has a validity date that runs out at the end of December 2011. I wonder if it will actually work?! Overall I think the card itself looks good, connectivity is good especially as the relevant adaptors are included in the box. To close out this portion of the "review" I thought I would post a picture of the card in my case. The case is a Fractal Design Define R3. (Yes I know I am still running the stock Intel cooler. I really need to get an better one but for now it does its job admirably). Now onto the Eyefinity performance. I should point out that I have only run performance numbers for BF3 & Arcania (Gothic 4) at the moment. I will look at some other games at a later point. I will not be running any synthetic benchmarks as quite frankly I find them a waste of time. Anyway onto BF3: Benchmark is a 5 minute FRAPS run through ( I actually play the game) taken from The first real level - Operation Sword breaker. I have found performance in this level to be nigh on identical to performance online so it should be a good indication of what you can expect in "real world" scenarios. Resolution is: 3560x1920 (technically 3588x1920 but I won't split hairs) Settings: All high bar Shadows and Decoration which are on medium. No Deferred AA, Medium Post AA no HBAO/Motion blur (the latter makes feel very queasy). System setup: Per Signature Drivers: HD6970 - 11.11a / HD7970 - "On disc" - 11.12 "HD6970 Playable Settings" HD6970 Min - 26.00 Avg - 35.54 HD7970 Min - 34.00 Avg - 46.63 (+31.2%) First up I was genuinely surpised at how well my HD6970 held up at this resolution / settings combo, 36FPS isn't exactly bad all things considered. Look at the HD7970 fly though, 31.2% faster at the same settings running the "on disc" drivers (which appear to be Cat 11.12). Ultra settings up next: Ultra Settings without AA (SBAO not HBAO) HD6970 Min - 16.00 Avg - 27.83 HD7970 Min - 22.00 Avg - 36.96 (+32.8%) Interesting results here. Firstly the performance delta has increased to ~33% which is excellent. The biggest suprise was the fact that I can now play at "Ultra" settings without AA at roughly the same level of performance as my HD6970 managed at High/Medium. Great stuff TBH. Ultra Settings with 4x AA - AKA "LOL" Settings HD6970 Min - 8 Avg - 14.68 HD7970 Min - 15 Avg - 20.21 (+37.7%) Well, I have nicknamed this "LOL" for a reason. My HD6970 simply ran out of VRAM and despite posting a average FPS of 14.68 it was completely unplayable (hard to play to even get the result TBH). The HD7970 ends up 37.7% better at this setting but in minimum terms it is 87% faster. Overall though this is academic as neither card can manage this setting. VRAM usage on the HD7970 peaked at 2400MB. Overclocked Performance: "HD6970 Playable Settings" HD6970 Min - 26.00 Avg - 35.54 HD7970 Min - 34.00 Avg - 46.63 HD7970 OC @ 1075/6000 Min - 38.00 Avg - 52.98 (+49%) ***Update regarding CPU Overclocking results:*** "HD6970 Playable Settings" HD7970 OC @ 1075/6000 Min - 38.00 Avg - 52.98 HD7970 OC @ 1075/6000 with 2500k at 4GHz Min - 38.00 Avg - 52.97 Small caveat - For reasons I am looking into (possibly PSU related) I am unable to run my card with the core at 1125. It technically runs but the voltage is too low to be stable (stock is 1.112 but it runs at 1.047). Finally we can see the HD7970 start to stretch its little legs. At the this OC level it ends up being ~ 50% faster than the HD6970 at the same settings. More importantly, the minimums are now higher than the average on the HD6970!. It is amazing to see over 50fps at this resolution on a single card and what is basically "high"settings. Overall BF3 Eyefinity performance has left a massive smile on my face which at the end of the day is what really matters. I can finally really enjoy Eyefinity in my favourite game currently which is just fantastic. I have also run some Eyefinity benches on a game that no-one is probably playing but I am. I got this game for under a fiver in the Steam holiday sale along with the rest of the Gothic line-up and was amazed when it literally brought my HD6970 to its knees. I thought I would include the results as a point of interest so here they are: HD6970 Min - 19.00 Avg - 27.30 HD7970 OC @ 1075/6000 Min - 30.00 Avg - 38.76 (+42%) Another instance where the minimum on the HD7970 is higher than the Average on the HD6970. You may note a lack of stock HD7970 benches for this game. The reason is simple - it took a number of attempts to get the game to play (thanks to a small change in resolution due to bezel management) and once it finally opened I couldn't see FRAPS sigh. Overall the HD7970 (OC) is 42% faster than the HD6970 in this game. Now the benches I have run had been put to bed I can move onto the conclusion. Based on my own experiences I am very pleased with the performance that the HD7970 has offered in Eyefinity. It has shown itself to be much faster than the HD6970 it replaces whilst pulling similar levels of power and outputting similar levels of heat. My own PSU issues aside it also clocks like it has 100 weight of TNT up its bottom. The price is obviously the biggest sticking point for a lot of people. At £500 there is no way I would purchase this card. At £450-£475 (where alot of them are residing) I would be very reluctant to part with my own money but at £450 and under I can see the attraction. Now, I got my card for a relative steal but can still see why it has been priced like it has. Who is to blame for the pricing is still up in the air with alot of fingers pointing to the UK retailers taking a nice chunk. Pricing in the US seems much more reasonable at $479-$500, so it does look like a case of "rip off Britain" once again. Would I recommend the HD7970 to anyone potentially interested in it? Yes but only if they are running a resolution that actually requires it and only if they don't pay more than £450. Anywhoo I have come to the end of my "little" (LOL) review of the HD7970. I hope you have found the content interesting. If you have any queries please feel free to ask in this thread or my PM.
