Durango’s GPU Sliced Open in New Report

By   /   Feb 4, 2013

In an exclusive report, VG Leaks have spilled the beans of the capabilities and performance of Microsoft’s next-gen console’s GPU.

The GPU is allegedly going to be clocked at 800 MHz, which is similar to the rumored specifications of Sony’s next-gen console. However the Durango will boast just 1.2 TFLOPS opposed to 1.8 TFLOPS of the Orbis (codename for the PS4).

“Durango GPU is a departure from previous console generations both in raw performance and in structure,” claims the report.

Instead of the traditional VRAM, Durango contains 32 MB of fast embedded SRAM (ESRAM); which carries an advantage of lower latency. That in turn helps speed up things quite a bit when texturing, rendering and reading. Interesting thing to note is that the ESRAM will not only offer services to GPU but also to other components in the console as well.

L1 and L2 are two caching systems that the GPU unit features. The L1 cache is used “exclusively for data read and written by shaders” whereas the L2 cache acts as a write-back when the GPU modifies data in its cache lines.

Compared to the current Xbox 360, Durango’s L1 and L2 caches receive texture data in compressed forms. Whereas on the Xbox 360 the texture data is decompressed and gamma corrected before reaching the intended cache. This eventually has Durango’s L1 cache “behave like a much larger cache when compared against previous architectures.”

As expected of next-generation hardware, the new Xbox also supports Antialiasing up to 2x, 4x and 8x MSAA levels. In addition it also features a modified MSAA type called compressed antialiasing which “combines most of the quality benefits of high MSAA levels with the relaxed space requirements of lower MSAA levels.”

Previously VG Leaks revealed the system specifications to Nintendo’s Wii U as well. However, there is always the chance that Microsoft ends up with offering something different. So far the GPU unit of the new Xbox looks marvelous but compared to power, the new PlayStation overshadows it a bit.
