PowerColor HD4870 PCS 1GB

In PCGH test, the Radeon HD 4870 is already very well and the more expensive Geforce GTX 260 times one after another bought from the cutting. Fans der neuen Radeon-Reihe mussten sich jedoch einige Wochen gedulden, bis es nun mit Powercolor dem ersten AMD-Partner gelang, ein eigenes Design der HD 4870 auf den Markt zu bringen. Fans of the new Radeon series but had to wait several weeks until it is now with Power Color the first AMD partner succeeded in creating one's own design of the HD 4870 on the market

In addition to a full gigabyte GDDR5 memory, the PowerColor HD 4870 PCS OC also house the cooling solution PCS based on a zero-Therm model. Diese erreicht laut Hersteller bis zu 20 Grad Celsius geringere Temperaturen als der AMD-Referenzkühler - und das trotz einer erhöhten GPU-Taktrate des RV770-Chips von angepeilten rund 800 Megahertz. This according to manufacturer reached up to 20 degrees Celsius lower temperatures than the AMD reference cooler - and despite an increased GPU clock rate of RV770 chips target of around 800 megahertz

More information - for example for HD 4850 with two gigabytes of VRAM - there are at PowerColor. Details zum Erscheinungstermin, Preis oder endültigen Taktraten stehen noch nicht sicher fest. Details about the release date, price or endültigen clock rates are still not sure.

Toda catita a bixa.

Os modelos PCS e derivados para mim são uma desvantagem, porque a unica vantagem é arrefecer mais a placa, mas como o calor libertado é o mesmo vai haver a desvantagem de ele se espalhar pela caixa, ao contrário do cooler original que deita o ar quente fora.

4870 com 1gb .... Ora agora já estamos a falar bem

Mas é como o MJRL disse ....só tenho pena não ser uma solução com exaustão para fora da caixa.

pois sobretudo nesta época do ano!!!

Radeon HD 4850 2 GB GDDR3 review

It is always real fun to see that whenever a product becomes successful,
manufacturers will do anything to create as much diversity as possible;
obviously to catch attention and create products for any budget available.
Sometimes however, a manufacturer can go so far that you have to scratch
behind your ears, once maybe even twice and think "hmm, that's not gonna
work I think".

Today we have such a product in the house. The graphics card we will test
today is based on the immensely popular Radeon HD 4850. Probably the best
value card one can buy. These cards at default come with 512 MB gDDR3
memory. Now, I can see a manufacturer double up that memory to 1 GB. The
effect would be small but measurable when you play games in very high
resolutions. Then, there is an incremental step to that as well, and that's
what we'll test today. PowerColor released a Radeon HD 4850 graphics card
with, get this ... 2 GB of memory.

But hey, perhaps we'll see wonders. Will the step between 512MB and 2 GB
differ very much in overall performance?

Mass efect a versão 512 bate a todas res

RaceDriver Grid só a 2500x 1600 é que a 2GB ganha por escassos 10FPS

Crysis 1.2v conseguiu o mesmo framerate com variação de 2 a 3 FPS a favor da 2GB

Fuel of War a 2GB perde a todas as res

3DMark Vantage (DirectX 10) perde a de 2GB

Catalyst 8.8 under Crossfire particularly fast?

It looks like the next Catalyst, named 8.8, is very fast in Crossfire. It shall run very well with AMD's new graphic card HD 4870 X2.
Besides AMD shall integrate the safe mode powerplay 2.0.

Here is the leaked beta driver:

(Vista) http://www.pctreiber.net/filebase_redirect.php?fid=7569

Lembrem-se que isto ainda são BETA, por isso quem usar é por sua conta e risco.

Resultados das drivers 8.8.

We made a small test (3dmark Vantage) of a Radeon 4850 Crossfire System with the Catalyst 8.8 beta. We tested with a Intel Q6600 (3.8 GHz) and 4GB DDR3. The benches I've added. Look forward, the final Catalyst 8.8 can maybe a little bit better! The powerconsumption is the whole system.

Para ter um reduçao ainda consideravel no consumo de watts em idle, ja devem ter resolvido o problema do powerplay e agora ja baixa para as velocidades 2D!
É bem ATI!!!

o powerplay ja funciona bem !

Powercolor preparing HD 4850 with DisplayPort Written by Slobodan Simic Friday, 08 August 2008 12:37


Works at 650MHz for the core

Powercolor is preparing yet another card in its HD 4000 series lineup, an HD 4850 with DisplayPort and HDMI ports on the back plate.

The new card will use Powercolor's non-reference PCS cooling, courtesy of Zerotherm, and will be overclocked to 650MHz for the GPU. The card features a dual-slot design and a dual-slot bracket for the TV-out port. The PCS cooling is actually Zerotherm's GX810 copper based cooler and the card will probably come with 512MB of GDDR3 memory.

According to our info, the card should be available by the end of August, but the price is still unknown. This is how it looks.
