Radeon 5770, 5750 & Sapphire 5750

      It's been less than two weeks since AMD launched the first DirectX11 video card and followed it up with the 5850 graphics card shortly after. Now AMD is launching the next two models in their 5000 series of cards. Seems rather quick? We'd say so, it was months and months before lower mid-range cards were released by AMD in the 4000 series but here we see them incredibly accelerated and ready to go. We'll be looking at these new cards, the 5770 and 5750 as well as a 5750 from Sapphire.     As you can see these are some very competitive cards with specs in the range of the 4870 for both of them but with all the DX11 and low power benefits of the 5000 series. There are 80 less stream processors on the 5750. The 5800 series has 1440 stream processor units so it is quite a bit less than those.       We don't have time to go into the details but here are some of the new technologies DirectX11 will bring, which hopefully is much more succesful than DX10. So far, it still seems harder than not to notice the details and speed improvements don't really seem to be there.         Here is what the card looks like which I'd say is very similar in design to the 5800 series again except much shorter and it just requires one six pin PCI-E connector. This is Sapphire's box for the 5750 which is quite small and needs less accessories than ever with all the ports on the back of AMD's new cards.   At first glance you may thinks this is a non-standard design from Sapphire but it actually looks like what the rest of the 5750 cards look like. The 5750's don't feature a full heatsink covering the chip unlike the 5770. The PCB is also Sapphire standard blue.     Here's the back of the card which makes it look quite a bit like the Batmobile from the 1960's TV show.   We'd say incredibly similar. Someone over there must be a fan.   Every port but VGA are all the backs of all the new 5000 series cards including two DVI ports, an HDMI port, and a DisplayPort which is still not very popular on monitors. All these ports are for ATI's EyeFinity technology allowing you to add just about as many monitors as your budget can or cannot handle.   Another angle of Sapphire's card.   The bundle consists of a DVI-to-VGA adapter, molex to PCI-E power adapter, and a copy of Dirt 2 which supports DX11.   Here are the technical specs from AMD.       ATI Radeon?

Mother Board Asus M3A78-T Memory Corsair XMS 4GB CPU Phenom II X4 965 Video Card ATI Radeon 4850 Hard Drive Western Digital SE 16 750GB Case Tsunami Thermaltake Display Samsung SyncMaster 30"     Windows Vista 64-bit SP2 was our OS with the latest Catalyst drivers from ATI. V-sync was disabled.       We'll start off with Crysis, still the most demanding game on the market almost two years after it's debut. What do we see here? The 5770 does lag behind our Radeon 4890 but not that far behind. 5fps at 2560x1600, 7.5fps at 1920x1200, and another 7 or so at 1680x1050. At high with our CPU and this GPU Crysis at 1920x1200 is playable. The 5750 is basically a hair faster than the Radeon 4850 which came out last summer.     Left4Dead is Valve's newest game for another month until L4D2 comes out. No real surprises here, except the 4850 lacks further behind at 2560x1600 with only 512MB of GDDR3 memory.           Unreal Tournament 3 shows us very similar results as to before. The 5770 is really no match for the Radeon 4890 and might be better matched by the 4870 1GB.     Not a whole lot changes with Call of Duty: World at War either.       Patterns repeat for us with Resident Evil 5's benchmark except at 2560x1600 the lack of highspeed and memory onboard the 4850 totally shatters it's power at that higher resolution.     Power consumption was measured at idle with the system sitting 5 minutes into Windows Vista desktop not drawing power and load running through UT3 at 2560x1600.     Unsurprisingly the 5000 series cards have the lowest idle draw despite being more powerful than the 4850. We think we probably would have got lower numbers had we switched to Windows 7 for testing. At load these cards remain the lowest here with the 5750 not quite hitting 200W. The 4890 meanwhile tops out at 326W.     Conclusion:ATI seems to be on a roll and unlike Nvidia it is not slowing down. How quickly they've moved to DX11 cards for almost their entire product lineup is very impressive. Ultimately it looks like the 5770 is about on par with the 4870 and the 5750 is just above the Radeon 4850. Very impressive for mid-range cards that also tout DX11 support, plenty of display ports and EyeFinity technology, and very lower power idle and load cards. What isn't to like is hard to find unless of course you already own a 4870 or 4850 graphics card which makes these a hard decision as they are priced higher than a 4850 and about as much as a 4870 or 4890 and though they do offer better features and very similar performance, are you really going to use Eyefinity? Is DX11 really necessary? The main feature is more than likely the lower power draw which is great. But if you're starting from scratch or running a lower end card these are the ones to get. Pricing:The 5770 is priced at $159 and the 5750 at $129. For the technology and performance we consider these very good prices. The only real competition is from ATI's previous generation of cards.
