Closer look: Apple Mac Pro AMD FirePro D-Series dual GPUs

04/11, 5:43am

AMD FirePro D-Series power the Mac Pro to new performance highs

One of the many exciting new features of the Mac Pro (late 2013) is Apple's choice to opt for dual AMD FirePro workstation GPUs as standard fitment, which certainly caught the eye of many observers. The previous generation Mac Pros included the option to fit dual CPUs, but as you can tell from the radical external redesign of the Mac Pro that Apple has fundamentally rethought its approach to the Mac workstation. Apple has chosen to adopt a dual-GPU configuration as standard fitment to leverage the massive processing power in GPU architecture. The biggest performance gains in certain professional applications come through harnessing the processing power in GPUs, rather than the CPU. To this extent, Apple has worked closely with AMD to develop three custom GPU solutions for the Mac Pro, to help Mac users tap into the power of AMD's Graphics Core Next microarchitecture for parallel processing using the OpenCL framework.

Intel Ivy Bridge benched early, shows huge leap in graphics

03/07, 11:55am

Intel Ivy Bridge gets pre-release test

An unofficial, pre-release benchmarking of Intel's upcoming Ivy Bridge architecture has shown an overall speed up, but most of all in graphics. Testing at AnandTech of a 3.5GHz, quad Core i7-3770K desktop chip has shown that the Intel HD 4000 integrated video is about 20 to 40 percent faster than the 3000 video on a roughly comparable earlier Core i7 using the current Sandy Bridge architecture. While still trailing behind AMD's Fusion in an A8 chip, it's enough to make games playable that wouldn't have been practical otherwise, such as running Skyrim smoothly at 1680x1050 and medium detail.
