ATI Radeon HD 5670 - Is DirectX 11 really cheaply? (english version) 2010-03-08 8 2217 - 2 / 8 oldal

The manners demand that we should speak some words about the fresh newcomers’ appearance, characteristics, equipment, so we do this now, but focusing on the most important things only.

ASUS EAH5670/DI/1GD5

We can not speak lot of about ASUS 5670, because it is almost factory Radeon HD 5670. GPU codename ’Redwood’ went through enough considerable curtailment compared to HD 5770’s Juniper, if we said latter and it in connection with Cypress, there is halving, it is in the present case right too, shader number reduced from 800 to 400, which is a critical difference.

Texture units fell from 40 to 20, and ROP blocks from 16 to 8, so there is a „halving package” too. But the good news are halvings were not touced the memory controllers, and 5670 – like HD 5700 series — has 128-bit, and they are staying with GDDR5 chips, which can produce good bandwidth in high clock speed, so the GPU will not drown.

If we are talking about clock speed, Redwood GPUs have average frequency -775 MHz, the GDDR5 chips are working low key 4000 MHz compare to top cathegory. The production technology of course 40 nm, which vouch for the moderate consumption and the cool function, especially with that sized core, also it is good for AMD, because they can produce big selling number products in low price.

As you can see, reds touched properly to Redwood GPU, 128-bit memory controller, GDDR5 stayed, és manufacturers took 1 GB to the PCB, which is more than enough. Likewise good, that the circle of the services full was left over, so we may get an relatively cheaply DirectX 11 compatible card easily, which has DVI, D-sub and native HDMI connectivity with Dolby TrueHD and DTS-HD Master Audio signal transmission. Given the UDV2 accelerated videoplaying opportunity, and if we add low power usage (AMD datas: 14W in idle state and 61W in use), quiet firm and little size, HD 5670 can got into a HTPC easily. If it stil not enough, we can not forsake Eyefinity, it can be used on three display maximum. 3D performance is one thing, we can not forget we speak about issue of HD 4670 in the down catherogy, so it is not specifically a gamer card.

ASUS’ work based on AMD reference modell, usual red one, with rounded corners, with the mentioned D-Sub and HDMI (1.3) connectivity. Factory refrigerator solution sits on GPU, which looks like HD 4670 and HD 4770, but ASUS made a little modifcation, called „Dust-proof Fan”. This makes approximately, that the airstirring get some kind of special coating which has a repulsive effect opposite the dust, what increases plus 25% lifetime of the fan. On the printed circuit we found Samsung GDDR5 blanks with K4G10325FE HC05 serial number.

Core of the card got a technology called GPU Guard, it’s details are shrouded in mystery, but it is some kind of core fixed structurally provides protection. The “Fuse Protection technology”is an increased electricity protection, so the card is resistent against network mistakes and not waited environment impact.

Box of product fill to ASUS’ recently brand, black-red-brown color world, fighter sitting on a horse, and important features are not surprise. Content of box do not have any surprise neither, we can find the card, users guide, driver disc and usual cables.

ASUS EAH5750 Formula

It is more interesting product, EAH5750 has been dreamed with unique electronic printed circuit and unique refrigeration by engineers. It shows on the box, we will get difference for our money, card is racing in the blue carton, and the fan has Formula 1 car shaped item, Formula name derives from here.

Next to the picture we can find a „13% cooler” subtitle, it means the fan can works its job with that efficiency against the factory solution. The box has two layer, if we open up the first one, we can see a liquid area int he second layer, and there is where the card shows up itself, and on the other surface we can read some interesting information.

ASUS introduced Xtreme Design with P55 PCH’s arrival, 5750 Formula profits from that too. PCB is matt black, 6-pin PCI Express power socket is watching to the same direction with CroessFireX sockets, „up”. The Exclusice Formula Fansink” consequently has more uniqe innovation.

The first is the “Aerodynamic Cover Design”, which is the special car-shaped cover panel, ASUS’ engineers think this is raise the card’s efficiency too, the result is 107% air flow. The “Micro Surface Treatment Technology” is pertaining to the ribs, which is grooving 14% in side of efficiency.

As we mentioned at HD 5670,the “Durable Dust-proof Fan Design” is still here, so the fan eats dust less, works better and longer time. The black body’s corners rounded off too, so it will not cut your hand during a fast mending. These are just trifles, do not seem a big thing, but they contribute to that we get more comfortable hardware, which can give more for us, than a simple product.

Outputs did not change, D-sub,DVI, HDMI, there is everything we need except DisplayPort, but we can live without it. There is Samsung GDDR5 chips on the back too with K4G10325FE HC05 serial number, so we can find connection with ASUS EAH5670’s chip (and it is not certainly an advantage).

As we mentioned, inside and outside of the box is very uniqe and demanding, but contents list are not so large. We can find the usual discs, guides and a CrossFireX bridge, a molex-PCI Express power converter, and a HDMI-DVI converter. We think there is enough place int he box for a fresh game.
