More 6K love

AMD is bringing Radeon 6000-series goodness to the real mainstream market with the retail release of the Radeon HD 6450.

Already available to system builders in OEM form for a couple of months now, AMD is hoping this 'second-generation' DX11 GPU tickles the fancy of people who require a discrete video card with more oomph than integrated graphics.

Positioned as a Jack-of-all-trades GPU, the £35-plus HD 6450, available with 512MB or 1GB memory, is pushed as being particularly suitable as a cheap solution for multi-monitor setups, while still providing a modicum of DX11 application and gaming performance.

But the same positioning and thinking also applies to the Radeon HD 5450, released over a year ago, though this new model has a little more firepower under the hood.

A unique proposition

AMD believes this card has no price-comparable peer, for NVIDIA's genuine budget offerings centre around DX10 compatibility and Intel's Sandy Bridge graphics, while reasonable, are no match for the Radeon's well-balanced feature-set. We'll see if these bombast claims bear out when the HD 6450 hits the review dungeon.

Due to be made available in both fan-assisted and fan-less models - the add-in board partner has the choice - the HD 6450 pulls a maximum of 27W when going at full chat.

Tech aficionados may be interested to learn that, architecturally, it sits between the Radeon HD 5450 and HD 5550 GPUs. There are 160 stream processors clocked in at 625-750MHz. AMD keeps consistency with other models by allocating a 20:1 ratio of stream processors to texture units. On the back end the card has four ROPs which link out to either DDR3 or GDDR5 memory via a 64-bit memory bus.

Cheap upgrade to a proper GPU

But this talk of ROPs and SPs is missing the point somewhat. Rather, the UVD3 video-processing block and multi-display technology is where the focus should be; this ain't a proper gaming card, no matter what AMD says.

If you own a basic DX9 graphics card or have lacklustre onboard graphics and want to modernise your PC, the Radeon HD 6450 appears to tick many of the boxes required for an el-cheapo upgrade.

We'll know more once it runs the gamut of tests, but for now, the sub-£50 Radeon HD 6450 hits many of the right notes for an HTPC or very basic gaming card.

Well, let's see if they can *finally* get the htpc card right. Previous fanless radeons have had to drop features (video quality stuff) like mad to provide smooth video processing, yet on paper were always the perfect HTPC card. I went through the 3450, 4550, tested the 5450 and so on, and am currently using a GT430 as a stopgap.

It is very frustrating that they blather on about DX11 etc on a 35ukp card. Seriously, you're not going to game on them, and the only possible use is lightweight DX Compute (which is backwards compatible with DX10 cards anyways). These cards really only have one practical use - decent 2D video playback and image quality for HTPC and business-type users.

Fingers crossed this time round!
Hopefully this means that the HD6570 and HD6670 are being released soon.
D-sub? Ribbon cable?! :clapping:
Even if they are I wouldn't get too excited. Since these are still on the 20:1 texture ratio they're still based on the VLIW5 model, which means minimal new architecture. Don't get me wrong, I'm not sniffing at a doubling of the shaders in AMDs bottom-rung card, but on that basis I'd be surprised to see a 6570 /6670 with more than about 480 shaders, which isn't really going to set the world alight. Given that they're putting GPUs with up to 480 shaders in the Llano fusion parts, I can't really see them bothering with the low-mid range discrete market that much any more…
According to the reviews the HD6450 with GDDR5 RAM is similar in speed to a GT220. The HD6570 and HD6670 are already available in many pre-builds and have 480 shaders. The HD6670 looks like it is around the same speed as a 9800GT.
