The sub-$100 price in the GPU market may not be of interest to most people who frequent this site but much of the sales volume for both AMD and NVIDIA come from this crucial segment. Currently, there is no shortage of choice for value minded consumers with cards like the HD 5670, HD 5570 and newly released GT 440 vying for attention. AMD is now bringing their HD 6000-series to more affordable price points as they finish a complete rollout of refreshed architectures.

While the HD 6450 was introduced a few weeks ago, today we finally get a good look at two cards brandishing the new Turks-series core: the HD 6670 and HD 6570. These cards aim to improve upon their predecessors’ gaming performance while retaining AMD’s lead in areas like high definition playback multimedia integration. Neither will likely be popular as a stand-alone card for people who like building custom gaming rigs but they will prove to be invaluable for large system builders and OEMs.


For those of you hoping for something drastically different from the current crop of entry level graphics cards, there’s disappointment waiting in the wings with these new products. Both the HD 6600 and HD 6500 series are based off of the Turks architecture which is a slightly revised and expanded version of the outgoing Redwood design. As such, most of the specifications stay the same but the number of SIMD arrays has expanded in order to incorporate 20% more steam processors and four more texture units. This should help differentiate these new parts from the outgoing ones in certain situations.

As one can imagine, the HD 6670 will basically carry the HD 5670’s torch from this point forward while consuming a mere 2 watts more even though it packs significantly more transistors. The HD 6570 meanwhile is broken into two different SKUs: one with GDDR5 and a slightly less expensive DDR3 version which comes with a cut in power consumption as well. These HD 6500-series products will in essence take over from the HD 5570 while the HD 5500 series should be staying around for the time being.

While these new AMD cards may not be a substantial improvement over the previous generation, they seem to be taking a step in the right direction for the lower end of the current market. What makes should matters even more interesting is NVIDIA’s near lack of any competitive products at these price points.

AMD EyeSpeed & UVD3

AMD EyeSpeed



The Northern Islands family of GPUs has a whole stable of video playback features, and in order to keep them all under banner AMD created the Eyespeed brand. Eyespeed will be the all-encompassing term given to all of the multimedia enhancing technologies such as pre / post processing, transcoding and HD playback within a unified ecosystem.

Eyespeed is split within two main spheres of influence: leveraging parallel processing for improved performance and video decoding through AMD’s UVD3.


UVD3; UVD2 on Steroids



As many of you probably already know, AMD’s Universal Video Decoder has been around for years and is known as one of the most capable video processing platforms currently available. UVD is now taking the next logical step forward with an expanded list of accelerated codecs in addition to the ones which were already compatible with past iterations.

One of the main features which have been added to the newly minted UVD3 is the ability to decode videos which use MVC encoding. As part of the H264 / MPEG-4 AVC codec, MVC is responsible for creating the dual video bitstreams which are essential for stereoscopic 3D output. Supporting this standard brings AMD’s GPUs the ability to process Blu Ray 3D movies through a HDMI 1.4a connector.

MPEG-4 Part 2 hardware acceleration for DivX and Xvid codecs has also been added but there is no mention made about the Nero Digital codec. For the time being, we’ll assume that Nero Digital acceleration will be added at a later date.


AMD’s main focus for these new graphics cards and for future products is to go beyond simply decoding HD content and instead add high end image quality improvements prior to the signal reaching the display. Through the use of the compute resources within a given system, additional pre and post-processing can be done before outputting an HD video stream.


AMD claims the additional processing their products can accomplish will significantly boost overall image quality whether it is for a simple upscale standard definition image or a true high definition video stream. The HQV benchmark is a highly, highly, highly subjective metric in which to determine image quality but supposedly the HD 6000 series will simply destroy the competition once all of its video processing features are enabled.

From ATI Stream to AMD APP Technology

From ATI Stream to AMD APP Technology


As AMD is moving to all but abolish the ATI brand, a number of technologies are being renamed and rationalized. The Stream name was once given to ATI’s GPGPU compute initiative to differentiate it from NVIDIA’s highly successful CUDA environment. Things are about to change….a bit.


In order to carry on Stream’s torch, AMD Accelerated Parallel Processing or APP has been created. Yes, the whole “App” moniker has been used so much that it’s now becoming a bit of a cliché but in this case, it seems to be aptly translated. This is now an all-encompassing term which can be used for graphics cards as well as AMD’s new upcoming generation of Fusion APUs.

AMD’s new APP SDK v2.2 is about to hit developers’ doorsteps and with it will come the integration of OpenCL computing for both x86-based CPUs and GPUs. This is one of APP’s major benefits over NVIDIA’s competing solution as it can be leveraged for a heterogeneous environment where specific tasks are sent towards the processor which will complete them most efficiently.


From our understanding, Stream’s name may have changed but its goal to deliver high performance computing on the GPU through OpenCL, DirectCompute and other APIs is still very much alive and well. If anything, it has actually expanded now that AMD is able to leverage both their CPUs and GPUs under the same programming umbrella.

A Closer Look at the HD 6670 & HD 6570

A Closer Look at the HD 6670 & HD 6570



Both of these cards are pretty standard fare for lower mid range but it is good to see the slightly higher end version –the HD 6670- beings designed as a low profile card regardless of its massive heatsink. Also note that the HD 6670 will also come in a single slot, regular profile size.


One item that seems to be missing from these cards is the usual Crossfire connector which is used to bridge a pair of more of AMD cards together. This is because lower-end AMD cards have the ability to reserve part of the PCI-E bus for the Crossfire interconnect so in effect, two lower end cards can work together for increased performance but scaling will likely be affected. In addition, due to their low power consumption needs neither uses an auxiliary 6-pin PCI-E power connector.


Even though board partners will likely deviate from the reference layout, the reference versions of the HD 6670 and HD 6570 have a trio of different connectors: a DisplayPort, a DVI and a VGA. Hopefully, we will see some versions with a native HDMI connector but the reference layout does allow for an Eyefinity setup.

BattleField: Bad Company 2 (DX11)


To benchmark BF: BC2 we used a five minute stretch of gameplay starting from the second checkpoint (after the helicopter takes off) of the second single player mission up until your battle with the tank commences. Framerates are recorded with FRAPS.

DiRT 2 (DX11)

DiRT 2 (DX11)


Being one of the newest games on the market, DiRT 2 cuts an imposing figure in terms of image quality and effects fidelity. We find that to benchmark this game the in-game tool is by far the best option. However, due to small variances from one race to another, three benchmark runs are done instead of the normal two. It should also be mentioned that the demo version of the game was NOT used since after careful testing, the performance of the demo is not representative of the final product. DX11 was forced through the game’s config file. In addition, you will see that these scores do not line up with our older benchmarks at all. This is due to the fact that a patch was recently rolled out for the game which included performance optimizations in addition to new graphics options.

Metro 2033 (DX11)

Metro 2033 (DX11)


There has been a lot of buzz about Metro 2033 which has mostly centered on its amazing graphics coupled with absolutely brutal framerates on even the best GPUs on the market. For this test we use a walkthrough and combat scene from The Bridge level which starts at the beginning of the level and lasts for about 3 minutes of walking, running and combat. Famerates are measured with FRAPS and Advanced PhysX is turned off.
