However, if we use pixel shaders at least several instructions long, this penalty ceases to play any crucial role. Technological innovations A new algorithm of the F buffer that enables not to calculate this or that pass of the divided pixel shader for pixels that don’t need it. Normal maps are used to give characters and scenes high levels of detail without the performance hit that would normally be associated with using high-polygon models. Let’s see how fillrate depends on shaders: The new high-end R4x0-generation arrived with the X series, equipped with various core tweaks for slightly higher performance than the “R”-based X series. Consumed Power, Energy Consumption:

The R design was a 4 “quad” arrangement 4 pipelines per quad.

ATI Radeon X800 PRO AGP

Consumed Power, Energy Consumption: But we repeat that overclocking depends on each particular card and you can’t make general conclusions basing on just one of them.

So we put dots, not dot here, and will continue tests when the rival arrives. It doesn’t win in old games though shows over fps anywaywe guess those who will buy it will think of the future. BioShock Infinite and Metro: Because DirectX Texture Compression DXTC was block-based and not designed for a normal map’s different data properties, a new compression method was needed to prevent loss of detail and other artifacting.

Pixel Shaders test The first group includes 1. Now let’s take a look at the cooling system and see what has been changed here. With R’s and RV’s 6 vertex shaders combined with higher clock radeob than the previous generation, ATI was able to more than double the geometry processing capability of XT. Unfortunately, the card is hard to overclock, and even minute frequency changes result the driver bringing the frequency back to the initial level.


Of course, MSAA modes compress both colour and depth data, and in the best-case scenario compression coefficient is close to the number of MSAA samples and makes 6: However, this is natural and should have been expected.

Either its price has to crash down, or the f420 will disappear from the market whatsoever, thus paving the way for a reduction in X PRO prices. Here’s what RivaTuner responds with: Test results Before we briefly comment the 2D quality I’ll repeat that there’s currently NO fully-fledged methods to evaluate this feature objectively because: And now the most complex rr420 with three light sources, in static and dynamic transition variants: It is not a package, it is a real bag which can be transformed into a backpack.

Note, ATI’s “Temporal AA” was actually a temporal dithering filter for spatial AA, not de facto temporal anti-aliasing which must involve a controlled blending of the temporal subsamples from consecutive screens. Point Sprites test Sprites ceased to be popular innovation and often lose to triangles in the performance ayi.

Here is the general view of the PCBs: Retrieved from ” https: The time will tell.

It’s impossible to say which approach is better. HSR algorithm hasn’t changed significantly.


Conventional texture compression methods are only made for standard textures. Now let’s get back to our scheme and look at its lower part.

A new method of 3Dc texture compression designed specially to compress two-component cards of the normals. Pixel shader, version 2.

In the next article we’ll conduct a big test only in new games and benchmarks. There’s no sense in comparing them as the victory raseon any accelerator is of no interest if performance is too high. Almost all modern 3D accelerators can have 2D quality vary from card to card 2D quality depends not only on graphics card, but also on monitor and cable in-between Recently monitor-card units have been affecting this feature very noticeably, because some monitors just “don’t like” some graphics cards.

Radeon X800 Series

The phase pixel pipeline described above is very close to 1. Finally, the ultimate eight trilinear filtered textures: And Z and stencil buffers have performance twice higher than the base filling rate of 32 values per clock the same as in NV The chip came equipped with over double the pixel and vertex pushing resources compared to the Radeon XT’s R a minor evolution of the Rwith 16 DirectX 9.

It is a High-End product, though not a first-rank and not even a second-rank one.
