In its most basic terms, you could quite easily consider the RV515 core that powers the Radeon X1300 as simply quarter of an R520, due to its featuring a single quad of pixel pipelines complemented by four texturing units (compared to four quads of pipelines and sixteen texture processors on R520) and two vertex shaders (against eight in R520). Each pixel shader unit within the core has the same ALU configuration and abilities as the rest of the Radeon X1000 series. The Ultra Threaded Despatch Processor used by R520 is also present in RV515, but again its abilities are a quarter those of its big brother, with it being capable of processing 128 threads here compared to 512 in R520 and R580.
One area where RV515 does miss out over its more powerful siblings is with regard to the memory controller – The ring bus controller used in RV530/RV535, R520 and R580 is absent here (no doubt due to the massive amount of die space it occupies), replaced by a more traditional crossbar controller which is 64-bits in width in this instance.
In terms of feature support the X1300 is largely identical to the rest of the Radeon X1000 series, from Shader Model 3.0 capabilities down to the ability to perform floating-point blending (with multi-sample anti-aliasing no less!). The X1300 also features the same anti-aliasing and anisotropic filtering abilities of the rest of the family, including the rotationally invariant ‘High Quality’ mode. Indeed, compared to R520, RV515 actually holds one feature over it – Fetch 4, present on all ATI’s current product line-up aside from the Radeon X1800, makes an appearance here too. If you want to read more about the functionality of Fetch 4, take a look at our Radeon X1900 XTX review. The Radeon X1000 series architecture itself is covered in more detail here.
