] GPUs allow branching, but usually with a performance penalty. Branching should generally be avoided in inner loops, whether in CPU or GPU code, and various methods, such as static branch resolution, pre-computation, predication, loop splitting, [43] and Z-cull [44] can be used to achieve branching when hardware support does not exist.
Graphics processing units (GPU) have continued to increase in energy usage, while CPUs designers have recently [when?] focused on improving performance per watt. High performance GPUs may draw large amount of power, therefore intelligent techniques are required to manage GPU power consumption.

CPUs that have many execution units — such as a superscalar CPU, a VLIW CPU, or a reconfigurable computing CPU — typically have slower clock rates than a sequential CPU with one or two execution units when built from transistors that are just as fast. Nevertheless, CPUs with many execution units often complete real-world and benchmark tasks ...
3DMark Port Royal is to test and compare the real-time ray tracing performance of any graphics card. [23] January 8, 2019 Windows 10 October Update DirectX Raytracing: Supported 3DMARK Steel Nomad [24] Steel Nomad, the latest GPU benchmark from 3DMark, is the official successor to the popular Time Spy tool, which was introduced eight years ago ...
Integrated graphics chip moved from motherboard into the processor. Improved gaming performance; Can access CPU's cache; Each EU has a 128-bit wide FPU that natively executes eight 16-bit or four 32-bit operations per clock cycle. [20] Hierarchical-Z compression and fast Z clear [21]
This level of performance is primarily enabled by the cumulative effort of a vast array of powerful GPU and CPU units. [71] As of December 2020, the entire BOINC network averages about 31 petaFLOPS. [72] As of June 2018, SETI@home, employing the BOINC software platform, averages 896 teraFLOPS. [73]
The NEC μPD7220 was the first implementation of a personal computer graphics display processor as a single large-scale integration (LSI) integrated circuit chip. This enabled the design of low-cost, high-performance video graphics cards such as those from Number Nine Visual Technology. It became the best-known GPU until the mid-1980s. [9]
