Mainstream Mobile GPU Research Analysis

The current development of mobile phones far exceeds the expectations of most people. The emergence of quad-core CPUs has reached 2 gigabytes of memory. This is something we could not imagine in the past. But in addition to CPU and memory, we often overlook a very important role - GPU, mobile device GPU is a part of the SOC, but not the same as the computer, the same CPU can match a variety of graphics. Here we introduce the characteristics of the mainstream mobile GPU, combined with the actual game performance analysis, so that readers are more aware of the choice of equipment.

ImaginaTIon's POWERVR series GPU is a star product on mobile GPUs. Its powerful performance and good compatibility make them widely used in various mobile phones and tablets. The most familiar ones are the iPhone and iPad series, from the iPhone generation. PowerVR MBX-Lite to The New iPad's POWERVR SGX543MP4, POWERVR series GPU has been giving Apple a strong graphics processing support, and Samsung's "Galaxy" first work Galaxy S is also using POWERVR SGX540. The POWERVR SGX544 is the top model in this series, with a triangular output rate of 88 M/s, pixel fill up to 1250 M/s, and a single-core triangular output rate higher than the dual-core POWERVR SGX543MP2 used by the Apple iPhone 4S. The iPhone5 uses the high-frequency version of the POWERVR SGX543MP3. The iPad4 is temporarily unknown. It only knows that it is quad-core, and it may be the SGX543MP4 high-frequency version or the SGX544MP4.

Exclusive Game - Geforce ULP Series

Geforce is a well-known name. Many of our PCs use Geforce chips, but on mobile devices, Geforce does not appear to be so "landscaped". Even in the dual-core CPU era, Geforce ULP with Tegra2 even It was a relatively weak GPU at the time. Tegra3's Geforce ULP is a lot stronger, and the data is "pleasing", but the actual application of performance is quite satisfactory, compatibility is relatively good performance, and there are many exclusive games with "THD" ending, overall performance It's still good.

Geforce ULP series features: Since Tegra series SOCs are ahead of each other in multi-core releases, Geforce ULPs have a wide range of devices, high game support, and exclusive game "care", which is more suitable for gamers. a GPU.

Geforce ULP texture compression format: DXT, universal ETC1.

Geforce ULP series mainstream devices:

Geforce 12sp : 71M/s triangle output, 1200M/s pixel fill (XOOM, Atrix 4G)

Geforce 16sp : 120M/s triangle output, 1600M/s pixel fill (One X, Nexus 7, OpTImus 4X HD)

Super data - Adreno series

Qualcomm's Adreno series is the exclusive GPU like the Geforce ULP. Only Qualcomm's SOC will be used. Among them, Adreno 225 and Adreno 320 are the star products used on the latest Qualcomm S4 platform. Qualcomm's SOC equipment is very large, and the equipment using Adreno 320 will It will come out at the end of this year. It has terrible data performance. However, due to insufficient support for Adreno series GPUs in some games, super performance is not available, but from the perspective of development prospects, the future of Adreno equipment is still very bright, because the new generation of “brothers” LG Nexus 4 will With Adreno320, game makers will definitely optimize for this platform in the future.

Mainstream Mobile GPU Research Analysis

Adreno series features: The data performance is good, new game effects support general, there are a small number of exclusive games, development potential is huge.

Adreno series texture compression format: own ATITC, universal ETC1.

Adreno series mainstream equipment:

Adreno220: 88M/s triangle output, 532M/s pixel fill (SensaTIon, Optimus LTE)

Adreno225: 130M/s triangle output, 760M/s pixel padding (Padfone, One S)

Adreno320: 200M/s triangle output, 3200M/s pixel fill (millet 2, Optimus G, Nexus 4)

Future Star - Vivante GC Series

This is a relatively rare GPU, which is mainly used on some domestic devices. The Huawei K3V2 uses a high-end version of the GC4000, which is very powerful. However, due to the relatively small number of devices that use this GPU, some game support is insufficient and some compatibility issues will arise. I believe that in the future, more and more devices using the GC series GPU will be able to shine. In addition, we can notice that the GC series supports the same texture compression format as the Geforce ULP series, which means that it is basically feasible to use the Geforce ULP game on the GC series.

"Parents" pedigree - Mali series

The Mali family was named because it is a GPU directly developed and designed by ARM. Therefore, there are many devices that support it. Of course, the most famous is the Samsung Exynos series of Orion. They use the Mali-400MP4 series GPU. , performance is very tough, once led the Android device. However, with the emergence of "Data Emperor" such as Adreno320 and GC4000, the Mali400MP4 has finally left the altar. At the time of Samsung’s Galaxy S II’s interview, many users complained that Mali400MP4 had poor compatibility and that most large-scale games could not be played. However, with the strong development of Samsung equipment, the current game manufacturers even optimized specifically for Mali400MP4, only it can "special effects fully open." This also shows that sometimes the data performance is not the most important, and more importantly, there is exclusive optimization.
