PowerVR is a division of Imagination Technologies (formerly VideoLogic) that develops hardware and software for 2D and 3D rendering, and for video encoding, decoding, associated image processing and DirectX, OpenGL ES, OpenVG, and OpenCL acceleration.

The PowerVR product line was originally introduced to compete in the desktop PC market for 3D hardware accelerators with a product with a better price/performance ratio than existing products like those from 3dfx Interactive. Rapid changes in that market, notably with the introduction of OpenGL and Direct3D, led to rapid consolidation. PowerVR introduced new versions with low-power electronics that were aimed at the laptop computer market. Over time, this developed into a series of designs that could be incorporated into system-on-a-chip architectures suitable for handheld device use.

PowerVR accelerators are not manufactured by PowerVR, but instead their integrated circuit designs and patents are licensed to other companies, such as Texas Instruments, Intel, NEC, BlackBerry, Renesas, Samsung, STMicroelectronics, Freescale, Apple, NXP Semiconductors (formerly Philips Semiconductors), and many others.

Technology

The PowerVR chipset uses a method of 3D rendering known as tile-based deferred rendering (often abbreviated as TBDR) which is tile-based rendering combined with PowerVR's proprietary method of Hidden Surface Removal (HSR) and Hierarchical Scheduling Technology (HST). As the polygon generating program feeds triangles to the PowerVR (driver), it stores them in memory in a triangle strip or an indexed format. Unlike other architectures, polygon rendering is (usually) not performed until all polygon information has been collated for the current frame. Furthermore, the expensive operations of texturing and shading of pixels (or fragments) is delayed, whenever possible, until the visible surface at a pixel is determined — hence rendering is deferred.

In order to render, the display is split into rectangular sections in a grid pattern. Each section is known as a tile. Associated with each tile is a list of the triangles that visibly overlap that tile. Each tile is rendered in turn to produce the final image.

Tiles are rendered using a process similar to ray-casting. Rays are numerically simulated as if cast onto the triangles associated with the tile and a pixel is rendered from the triangle closest to the camera. The PowerVR hardware typically calculates the depths associated with each polygon for one tile row in 1 cycle.[dubious – discuss]

This method has the advantage that, unlike a more traditional early Z rejection based hierarchical systems, no calculations need to be made to determine what a polygon looks like in an area where it is obscured by other geometry. It also allows for correct rendering of partially transparent polygons, independent of the order in which they are processed by the polygon producing application. (This capability was only implemented in Series 2 including Dreamcast and one MBX variant. It is generally not included for lack of API support and cost reasons.) More importantly, as the rendering is limited to one tile at a time, the whole tile can be in fast on-chip memory, which is flushed to video memory before processing the next tile. Under normal circumstances, each tile is visited just once per frame.

PowerVR is a pioneer of tile based deferred rendering. Microsoft also conceptualised the idea with their abandoned Talisman project. Gigapixel, a company that developed IP for tile-based deferred 3D graphics, was purchased by 3dfx, which in turn was subsequently purchased by Nvidia. Nvidia now uses a form of tile rendering in the Maxwell and Pascal microarchitectures.[1]

ARM began developing another major tile based deferred rendering architecture known as Mali after their acquisition of Falanx.

Intel uses a similar concept in their integrated graphics solutions. However, their method, coined zone rendering, does not perform full hidden surface removal (HSR) and deferred texturing, therefore wasting fillrate and texture bandwidth on pixels that are not visible in the final image.

Recent advances in hierarchical Z-buffering have effectively incorporated ideas previously only used in deferred rendering, including the idea of being able to split a scene into tiles and of potentially being able to accept or reject tile sized pieces of polygon.

Today, the PowerVR software and hardware suite has ASICs for video encoding, decoding and associated image processing. It also has virtualisation, and DirectX, OpenGL ES, OpenVG, and OpenCL acceleration.[2] Newest PowerVR Wizard GPUs have fixed-function Ray Tracing Unit (RTU) hardware and support hybrid rendering.[3]

PowerVR chipsets

Series1 (NEC)

VideoLogic Apocalypse 3Dx (NEC PowerVR PCX2 chip)

PowerVR's initial products were available as the OEM graphics on some Compaq models,[4] as an add-on card for other OEMs,[5] the retail VideoLogic Apocalypse 3D[6] card and the retail Matrox M3D[7] card.

Series2 (NEC)

The second generation PowerVR2 ("PowerVR Series2", chip codename "CLX2") chip found a market in the Dreamcast console between 1998 and 2001. As part of an internal competition at Sega to design the successor to the Saturn, the PowerVR2 was licensed to NEC and was chosen ahead of a rival design based on the 3dfx Voodoo 2. The PowerVR2 was peered with the Hitachi SH-4 in the Dreamcast, with the SH-4 as the T&L geometry engine and the PowerVR2 as the rendering engine.[8] The PowerVR2 also powered the Sega Naomi, the upgraded arcade system board counterpart of the Dreamcast. The quality and performance of the PowerVR was a major step ahead of contemporary PC graphics cards such as the RIVA TNT, Voodoo Banshee and Savage3D. However, the success of the Dreamcast meant that the PC variant, sold as Neon 250, appeared a year late to the market, in late 1999, and was by that time no better than the RIVA TNT2 or Voodoo3, though it managed to remain competitive.[9]

Series3 (STMicro)

Kyro II.

In 2001, STMicroelectronics adopted the third generation PowerVR3 for their STG4000 KYRO and STG 4500 KYRO II (displayed) chips. The STM PowerVR3 KYRO II, released in 2001, was able to rival the more expensive ATI Radeon DDR and NVIDIA GeForce 2 GTS on high in graphic benchmarks of the time, despite not having hardware transform and lighting (T&L). As games were increasingly optimized for hardware T&L, the KYRO II lost its performance advantage.

Series4 (STMicro)

STM's STG5000 chip, based upon the PowerVR4, did include hardware T&L but never came to commercial fruition. It and the KYRO 3 (2D/3D AIB) were shelved due to STMicro closing its graphics division.

MBX

PowerVR achieved great success in the mobile graphics market with its low power PowerVR MBX. MBX, and its SGX successors, are licensed by seven of the top ten semiconductor manufacturers including Intel, Texas Instruments, Samsung, NEC, NXP Semiconductors, Freescale, Renesas and Sunplus. The chips are in use in many high-end cellphones including the original iPhone, Nokia N95, Sony Ericsson P1 and Motorola RIZR Z8, as well as some iPods.

There are two variants: MBX and MBX Lite. Both have the same feature set. MBX is optimized for speed and MBX Lite is optimized for low power consumption. MBX can be paired up with an FPU, Lite FPU, VGP Lite and VGP.

PowerVR Video Cores (MVED/VXD) and Video/Display Cores (PDP)

PowerVR's VXD is used in Apple iPhone, and their PDP series is used in some HDTVs, including the Sony BRAVIA.

Series5 (SGX)

PowerVR's Series5 SGX series features pixel, vertex, and geometry shader hardware, supporting OpenGL ES 2.0 and DirectX 10.1 with Shader Model 4.1.

The SGX GPU core is included in several popular systems-on-chip (SoC) used in many portable devices. Apple uses the A4 (manufactured by Samsung) in their iPhone 4, iPad, iPod touch, and Apple TV, and uses the Apple S1 in the Apple Watch. Texas Instruments' OMAP 3 and 4 series SoC's are used in the Amazon's Kindle Fire HD 8.9", Barnes and Noble's Nook HD(+), BlackBerry PlayBook, Nokia N9, Nokia N900, Sony Ericsson Vivaz, Motorola Droid/Milestone, Motorola Defy, Motorola RAZR D1/D3, Droid Bionic, Archos 70, Palm Pre, Samsung Galaxy SL, Galaxy Nexus, Open Pandora, and others. Samsung produces the Hummingbird SoC and uses it in their Samsung Galaxy S, Galaxy Tab, Samsung Wave S8500 Samsung Wave II S8530 and Samsung Wave III S860 devices. Hummingbird is also in Meizu M9 smartphone.

Intel uses the SGX540 in its Medfield platform.[10]

Series5XT (SGX)

PowerVR Series5XT SGX chips are multi-core variants of the SGX series with some updates. It is included in the PlayStation Vita portable gaming device with the MP4+ Model of the PowerVR SGX543, the only intended difference, aside from the + indicating features customized for Sony, is the cores, where MP4 denotes 4 cores (quad-core) whereas the MP8 denotes 8 cores (octo-core). The Allwinner A31 (quad-core mobile application processor) features the dual-core SGX544 MP2. The Apple iPad 2 and iPhone 4S with the A5 SoC also feature a dual-core SGX543MP2. The iPad (3rd generation) A5X SoC features the quad-core SGX543MP4.[11] The iPhone 5 A6 SoC features the tri-core SGX543MP3. The iPad (4th generation) A6X SoC features the quad-core SGX554MP4. The Exynos variant of the Samsung Galaxy S4 sports the tri-core SGX544MP3 clocked at 533 MHz.

Series5XE (SGX)

Introduced in 2014, the PowerVR GX5300 GPU[12] is based on the SGX architecture and is the world’s smallest Android-capable graphics core, with substantial improvements in efficiency, providing an ideal low-power solution for entry-level smartphones, wearables, IoT and other small footprint embedded applications, including enterprise devices such as printers.

Series6 (Rogue)

PowerVR Series6 GPUs[13] are based on an evolution of the SGX architecture codenamed Rogue. ST-Ericsson (now defunct) announced that its Nova application processors would include Imagination’s next-generation PowerVR Series6 architecture.[14] MediaTek announced the quad-core MT8135 system on a chip (SoC) (two ARM Cortex-A15 and two ARM Cortex-A7 cores) for tablets.[15] Renesas announced its R-Car H2 SoC includes the G6400.[16] Allwinner Technology A80 SoC, (4 Cortex-A15 and 4 Cortex-A7) that is available in the Onda V989 tablet, features a PowerVR G6230 GPU.[17] The Apple A7 SoC integrates a graphics processing unit (GPU) which AnandTech believes to be a PowerVR G6430 in a four cluster configuration.[18]

Series6XE (Rogue)

PowerVR Series6XE GPUs[19] are based around Series6 and designed as entry-level chips aimed at offering roughly the same fillrate compared to the Series5XT series. They however feature refreshed API support such as Vulkan, OpenGL ES 3.1, OpenCL 1.2 and DirectX 9.3 (9.3 L3).[20] Rockchip and Realtek have used Series6XE GPUs in their SoCs.

Series6XT (Rogue)

PowerVR Series6XT GPUs[21] aims at reducing power consumption further through die area and performance optimization providing a boost of up to 50% compared to Series6 GPUs. Those chips sport PVR3C triple compression system-level optimizations and Ultra HD deep color.[22] The Apple iPhone 6, iPhone 6 Plus and iPod Touch (6th generation) with the A8 SoC feature the quad-core GX6450.[23][24] The MediaTek MT8173 and Renesas R-Car H3 SoCs use Series6XT GPUs.[25]
