Radeon X1300 Pro

In synthetic performance tests, when executing simple pixel shaders, the ATI RADEON X1300 PRO performed almost as well as the RADEON X700, which has twice as many pixel processors operating at 400 MHz. When working with complex pixel shaders, the new product proved to be ambiguous - some of these shaders are executed very quickly, others even slower than on GeForce 6600. Of course, when executing version 3.0 pixel shaders, the RADEON X1300 has an advantage, since it includes branch execution engine.

Despite the presence of only two vertex processors, the RADEON X1300 PRO performed well in geometric tests: it consistently outperformed NVIDIA GeForce 6600, and in some cases outperformed even the much more powerful RADEON X700.

The texturing speed of the RADEON X1300 PRO is comparable to the texturing speed of the RADEON X700 and GeForce 6600.

ATI managed to increase the clock speed of the RADEON X1300 PRO to 600 MHz, which is almost twice as high as that of the RADEON X300. This is made possible thanks to the 0.09-micron process technology, but do not forget that other models of the X1300 line have a lower GPU clock speed of 450 MHz.

As in the case with the more powerful RADEON X1800 and RADEON X1600, ATI has implemented the Ultra-Threading Dispatch Processor technology in the RADEON X1300, which ensures even distribution of the load between the ALUs of pixel processors. According to ATI's statement, such an architectural approach makes it possible to achieve 90% efficiency of pixel processors when executing any pixel shader.

The RADEON X1300 does not support the Ring Bus architecture and does not have a programmable memory request arbiter, but, like its older brothers in the RADEON X1000 family, it has a fully associative cache and an advanced implementation of HyperZ technology.

The use of a finer technical process allowed us to increase the power consumption of the RADEON X1300 PRO to 30 watts
