Eurogamer.es has had access to internal information about one of the secrets that Sony is now at hand. We refer to PSP2, but a hardware that has not yet been officially announced for PSP and should happen in the future PSPGo. With the data obtained could say that at this new portable graphic display could all the brute force of the first Xbox and counting at the same time with the most advanced Dreamcast.
Part of the information we have spoken of as an essential component in a video game system such as your graphics processor. In this case, based on a multicore version of SGX543 of Imagination Technologies, a provider, among other things, the graphics chips that fit the iPhone. Would have 4 cores and its internal code name is hydra. An approach to increase the peak performance of 133 million polygons per second, exceeding the original Xbox.
Pileup, we see that they have separate caches for data and textures, 8 PE ISP (Image Signal Processor Processing Elements) that significantly improves the fill rate, vec3 extensions / 4 in USSE (Unified Scalable Shading Engine) to double the actual performance vector shaders in the applications and will support OpenGL 2.0 and DX10.
The magic that usually include Imagination Technologies to exponentially increase the performance of its chips this time is given by the tile-based rendering, supported by this family of graphics chips and optimizations in the use of texture cache to reorganize the memory function their place in the final rasterizado. It also includes an old acquaintance of the users of Dreamcast, the now so fashionable Deferred Rendering. Recall that a solution to alleviate complex scenes eliminating overdraw not draw the geometry that is hidden in the final scene.
This information, of course, come from a project that is still under development, and that Sony has not yet confirmed or denied anything. Sony should not be delayed much beyond the end of the year to announce this new brand itineración portable Playstation.
Imagination did not reveal many details about its new design, the PowerVR SGX543 (5 for series, 4 for performance and 3 to indicate that it is part of the Power VR Extended product line), in terms of numbers since clock speed, resulting performance or power consumption largely depend on the specs a hardware designer chooses. But we were told that the shader performance has been increased by about 40% and that the GPU delivers about 2.5x the image processing performance of an ARM Cortex-8 CPU and outperforms the a 600 MHz ARM chip in some traditional CPU benchmarks with a 100 MHz design. Power consumption is also down, but company representatives indicated that “a huge leap has not been made”.
The new 543 isn’t about power consumption; it is about performance and features. It is multi-core capable - 543 chips can run in parallel - with power consumption and space constraints being the main limitations for the number of cores - and can translate into very capable hardware for devices such as netbooks, MIDs, set top boxes and mobile phones. According to Imagination, one core delivers a performance of 35 million polygons per second and a fill rate of 1 Gigapixel per second at 200 MHz.
