NVIDIA GeForce GTX 570 vs Intel HD Graphics 5300 vs NVIDIA GeForce GTX 580

NVIDIA GeForce GTX 570

Intel HD Graphics 5300

The Intel HD Graphics 5300 (GT2) is an integrated Broadwell graphics card revealed in late 2014. It can be found in Core M ULV SoCs such as the Core M-5Y70. While the GPU shines with its extremely low power consumption, raw performance is quite low and barely sufficient for modern games.

Architecture and Features

Broadwell features a GPU based on the Intel Gen8 architecture, which has been optimized in various aspects compared to the previous Gen7.5 (Haswell). Inter alia, the shader arrays called "subslice" have been reorganized and now offer 8 Execution Units (EUs) each. Three subslices form a "slice" for a total of 24 EUs. Combined with other improvements such as larger L1 caches and an optimized frontend, the integrated GPU has become faster and more efficient than its predecessor.

The HD Graphics 5300 represents the mid-range version of the Broadwell GPU family and consists of one slice with 24 EUs. Beyond that, there is also a low-end variant (GT1, 12 EUs) as well as higher-end models (GT3/GT3e + eDRAM, 48 EUs).

All Broadwell GPUs support OpenCL 2.0 and DirectX 11.2. The video engine can now decode H.265 using both fixed function hardware as well as available GPU shaders. Up to three displays can be connected via DP 1.2/eDP 1.3 (max. 3840 x 2160 @ 60 Hz) or HDMI 1.4a (max. 3840 x 2160 @ 24 Hz). HDMI 2.0, however, is not supported.

Performance

Depending on the specific CPU, the maximum GPU frequency varies between 800 and 900 MHz. Due to the very low TDP, however, the average clock in 3D applications will be significantly lower. Therefore, the HD 5300 just barely outperforms the old HD 4000 or HD 4200, but requires much less energy for the same performance.

Only a few games as of 2014/2015 will run fluently at low settings, e.g. Dota 2 or Sims 4.

Power Consumption

Thanks to a new 14 nm process, the entire Core M chip is specified at just 4.5 W TDP and is suited for passively cooled tablets. The TDP is flexible and can be reduced or increased, which has a significant impact on performance.

NVIDIA GeForce GTX 580

Die NVIDIA GeForce GTX 580 ist eine High-End Desktop Grafikkarte welche Ende 2010 vorgestellt wurde. Sie basiert auf den GF110 Fermi Chip im Vollausbau. Das heisst die 580 bietet 512 Shader, 64 Textureinheiten und 16 Polymorph Engines. As Besonderheit der Fermi Architektur werden die Shader doppelt so schnell getaktet wie der Rest des Chips (z.B. die Textureinheiten).

Die Leistung der GTX 580 liegt deutlich über der mobilen GeForce GTX 580M (welche eigentlich eine geringer getaktete GTX 560 Ti ist). Im Vergleich zur Konkurrenz liegt die GTX 580M etwa auf dem Niveau einer Radeon HD 7950. Die Nachfolgekarte der Kepler Generation namens GTX 680 kann sich mit etwa 30% Vorsprung deutlich absetzen.

Mit einem TDP von 244 Watt ist die GTX 580 eine der stromhungrigsten Grafikkarten und benötigt für den Betrieb ein starkes Netzteil.
