Amd Radeon Hd 7850 2 Gb

The Pitcairn little lad has arrived in the shape of the Amd Radeon Hd 7850 and it could well be a pint-sized powerhouse.

The Hd 7850 pretty much finalises Amd's current plans for the southern islands line up, bar the crazy-expensive dual-gpu New Zealand card which is likely waiting on Nvidia's new cards.

We may see some other odd little revisions once Nvidia's kepler cards start trickling out, just to fill some gaps, but this is going to be the last standard card for a while.

The Amd Radeon Hd 7850 is also the card that's arguably got the most chance of being successful out of this family. 

At the price it looks likely to retail at, the sub-£200 mark, it could well be the highest-selling of Amd's enthusiast-class cards.

Like the Amd Radeon Hd 7870 that we've already seen, the Hd 7850 is though going to face a lot of stiff competition at this price-point.

Pitcairn Pro is what you'll learn to know as the Radeon HD 7850, it features 16 Compute Units, 1024 Stream (shader) Processors, 64 texture units and 32 ROPs.  

It's core and memory frequencies fall behind that of the 7870 but is still clocked at a good 860 MHz core with 1.20GHz (4800 MHz effective) on the memory. 

The 7850 tested has 2GB of graphics memory, but for this model we expect to see both 2GB and 1GB memory variants in the stores, again the memory is based on a 256-bit interface.

The 7870 is expected to have an MSRP of $349 USD, whereas the 7850 will be available for $249 (2GB). 

Typically prices in Eur would be slightly lower.

Amd has been focusing on three primary features and key selling points ever since the series 5000 products were released. 

First off, the new graphics adapters are of course Directx 11 ready. 

With Windows 7 and Vista being Dx11 ready all we need are some games to take advantage of Direct Compute, multi-threading, hardware tessellation and new shader 5.0 extensions.

Another big feature of the product that you already learned about is of course eyefinity, the ability to connect many monitors (depending on AIC/AIB choices in outputs) to your videocard and use it in a desktop environment, or to create an incredibly wide monitor resolution to play games in. 

The third big and prominent feature is of course performance for money. 

It's new, it's affordable, it has Amd written all over it.

Head on over to the next page where we'll meet and greet Pitcairn, aka the Radeon HD 7800 series.

While the Hd 7700 series left us feeling overall pretty flat, the same can't be said for Amd's new Hd 7900 series which offered us awesome performance. 

Along with strong numbers, though, we saw the new 28nm based cards run cooler, quieter and draw less power at both idle and load, they impressed us a lot.

We've got our fingers crossed that the Hd 7800 series sits more in line with the Hd 7900 series than it does the Hd 7700 series. 

Of course what's really going to matter is the performance of the new model. 

Before we look at that, though, we need to see what's going on with the card itself. 

While we'd normally start off with the packaging, because we're dealing with a reference card from Amd, we don't have one. 

Once we've looked at the card and taken a closer look at the main specifications, we'll move into our testbed, which then of course leads us into the performance side of things.

Well, that just about covers that, so let's just take a closer look at the card and see what exactly is going on with this new series and model from Amd.
