AMD Radeon HD6570 reviewed
recently upgraded to some AMD Radeon HD6570 from the nVidia GeForce 9400GT which chose to go kaput, and I need to say, this card includes rewards for those who can seek them.
Let's start having a little bit of background. The Northern Islands number of GPUs, that are sold because the HD6XXX number of AMD Radeons, would be the second-generation DirectX 11 GPUs from ATI,[link widoczny dla zalogowanych], that are built on the 40nm SOI process. The GPUs are collectively codenamed Northern Islands; in fact the Northern Islands GPUs consists of the Turks, Caicos, Cayman, Barts and Antilles GPUs. They support Direct3D 11, Shader Model 5.0,[link widoczny dla zalogowanych], OpenCL 1.1 and OpenGL 4.1. In addition, much like nVidia's PureVideo, AMD also supports accelerated H.264 and XviD decoding on these cards because of their Universal Video Decoder (UVD), that has been bumped to version 3. Cards with HDMI offer the HDMI 1.4a spec. As for support for the upcoming Windows 8, Windows 8 should really feature DirectX 11.1; it is currently unknown whether DirectX 11.1 may have additional hardware requirements along with DirectX 11 (remember, Microsoft actually marketed Tessellation as a DirectX 11 feature, but it was actually introduced included in DirectX 10.1, which came included in Windows Vista Service Pack 1). Obviously, Windows 8 works just fine with DirectX 11 cards; it's the games that will require the entire gamut of DirectX 11.1 features.
The AMD Radeon HD6570 features the Turks GPU. The Turks GPU was launched on February 7th, 2011 - so it's actually quite old by gaming standards. Anyway this card is marketed because the highest entry-level card from the Northern Islands series. That it is quite a bit more, as we'll see later, but let's get to see the card first.
This card comes in a full-height single-slot package. It requires, like all cards,[link widoczny dla zalogowanych], a PCIe x16 connector, but it does not need an external PCIe power connector for graphics cards. Considering its performance, this is quite surprising. The present generation nVidia counterpart with this is the GT440, but by all benchmarks, the GT440 has a higher power draw, higher heat generation and performs slightly worse than the 6570. This card is priced somewhat low, and isn't really that sort of a high-end card to warrant buying overclocked editions from vendors like ASUS or MSI. But on the other hand, with a 650MHz core clock along with a 1GHz memory clock, this card does lend itself well to overclocking. Think about this: this card and the HD6670 both feature the very same GPU. But the 6670 is clocked at 800MHz, and priced $20 higher (in India,[link widoczny dla zalogowanych], you can expect the 6670 to cost 2 grand a lot more than the 6570). The 6570 is available in a 1GB version along with a 2GB version, whereas the 6670 will come in a 1GB version only. The one that I bought features a gig of GDDR5 memory - the 6570 has a GDDR3 version also. The GDDR5 version draws in regards to a watt more of power,[link widoczny dla zalogowanych], but hey, if you're able to overclock your 6570 to 800MHz, you've got a 6670! Believe me, the clock may be the only difference between the 6570 and also the 6670. The ATI Catalyst Control Center maxes out at 750MHz,[link widoczny dla zalogowanych], however i was able to achieve a stable overclock at this frequency. Given that the 6670 can be overclocked by around 25-30 MHz, theoretically, you can, by using third party tools, take the 6570 from 650 to 830MHz. And that is a massive FPS boost in games, let me tell you. I'd say the 6570 is an extremely sweet deal at 5 grand Indian bucks.
For heat dissipation, this is almost winter and I've got a pretty cramped stock "baby cabinet" with a 600 Watt CoolerMaster PSU saved in a cramped corner without any fan - in other words, the worst of all that could happen with regards to airflow - and the card looks after a stable 60 degrees Celsius under load. In idle, it can be anything from around 45 to 50 degrees. That's cool, by all standards. Since the optimal temperature maxima is 85 degrees,[link widoczny dla zalogowanych], and absolute maxima is 105 degrees. This means you have a lot of room.
The credit card draws around 10 watts of power at idle, but could spike to 70 watts at full load, so be sure you have a PSU able to handle it - for those who have a stock 400 Watt PSU, ditch it for a Antec or CoolerMaster. 400 Watt is the minimum required, and also you need it to become pretty efficient. Because it requires no external power connector, it does need a lot of power off your motherboard.
About the technical side, the GPU has 716 million transistors, a 118 square mm die, a pixel fill rate of 5.2 gigapixels per second, a texture fill rate of 15.6 gigatexels per second. It has a 64GB/s bandwidth in the GDDR5 version, along with a 28.8GB/s bandwidth within the GDDR3 version (which for any 200 rupee difference doesn't actually make much sense). It runs using a 128 bit wide bus.
As for connectors, the credit card comes with 3 - one each of VGA,[link widoczny dla zalogowanych], DVI-D with Dual Link support, as well as an HDMI connector with 7.1 channel multichannel audio output. It's also built with support for stereoscopic 3D output.
Digital Media
Unlike these card (the GeForce 9400GT),[link widoczny dla zalogowanych], that one isn't a card for digital media - its about as expensive like a HTPC card, but its too darn good to become relegated to hardware assisted Blu-Ray playback. Don't misunderstand me - AMD Avivo HD is actually good and works really well. But if you want a card solely for the purpose of powering a gigantic 1080p display, you want something worse.
However, if you are creating a multi-monitor setup for digital video creation,[link widoczny dla zalogowanych], continue reading. Avivo HD not only decodes digital video, but encodes it too, so you'll strike gold with this particular card if you're utilizing it inside a studio environment. Actually, this card works well in Mac Pros too, so you can make use of this on Windows PCs and Macs and Adobe Premiere and to some degree Photoshop too can make use of the exceptional image processing capabilities of the card.
Gaming
If you have a low-resolution monitor (I'm talking no more than 1366x768),[link widoczny dla zalogowanych], this can be used card and max your game's settings and obtain around 30-35fps off just about all games. For those who have a 1440x900 display, you'll want to overclock the card a tad, and you'll be in a position to max out the game. If you have a full HD monitor - well, this card is not a dedicated gamer's card, but you will still get 25-30fps if you sculpt the settings to medium.
This card excels at anisotropic texture filtering and full-screen antialiasing. Yes, that is correct. Anisotropic texture filtering and Antialiasing performance has been a strength of ATI Radeons since the legendary HD4870, but with this card, the performance penalty is under 1fps at 1366x768. I attempted this with Crysis Warhead - which using its ample foliage is a very edge-heavy game, company, at Enthusiast (the most possible) settings, I got around 25fps. This really is remarkable for any card this cheap.
However, there's one game that simply refuses to give any graphics card a great day, and that is Microsoft Flight Simulator X. Despite a couple of unofficial mods to improve rendering, I possibly could get only 8-9fps at densely populated areas and landscapes and at airports (it actually dropped to less than 1fps over Hong Kong). This really is at 1024x768, with all the settings topped out.
Overall, I attempted out a few old games (Requirement for Speed: Most Wanted and Carbon), Crysis, Crysis Warhead, in addition to Crysis 2, Cod 4: Modern Warfare and Mw2 (in fact,[link widoczny dla zalogowanych], I bought this card due to the impending Modern Warfare 3 release), together with F1 2010. I could max the game everywhere except Crysis 2, and it played well around 25-30fps in all the first-person shooters, and well around the 80fps mark within the NFS titles. It was without overclocking. The card's elaborate packaging says FreeBSD is supported, there is however no Catalyst drivers for FreeBSD. FreeBSD comes with access to the open source Radeon driver (like Linux), however the Radeon drivers have as of this moment major beef with the Northern Islands cards, and therefore are for all practical purposes unusable.
Mac OS X features support for this card because the 10.6.8 release.
The Verdict
The 6570 is a good card. In Kolkata, it cost me INR 5050 inclusive of taxes, and after overclocking, it's giving me the performance of the card which should cost you a ton more. So should you buy it? A high level serious gamer, no. A high level casual gamer,[link widoczny dla zalogowanych], yes, especially if you want to play your game well. If all you want would be to watch HD movies,[link widoczny dla zalogowanych], then no, but when you rip Blu-Rays, or do extensive photoshopping, or operate in a studio environment with full HD monitors,[link widoczny dla zalogowanych], then yes. In short, if all you do is gaming, then you definitely should purchase something better. But when you're a power user who expects to play games once in a while, and wants to thoroughly benefit from the gaming experience, you best buy this at this time.相关的主题文章：
