s3_logoS3 представиха последната си линия “дискретни” енерго-спестяващи графични процесори – Chrome 5400E GPGPU с поддръжка на OpenCL 1.1 произведени по 65nm low-power технология.
Макар че S3 не са известни с особено високопроизводителни продукти в desktop сегмента на пазара, решенията на компанията се ползват доста успешно при embeded и ултракомпактни устройства от всякакъв вид, заради изключително ниското потребление на електроенергия, ниските си работни температури, и не на последно място – невисоката си цена. Според компанията това е най-гъвкавият и бърз графичен процесор за embeded решения и за сега предлага най-доброто съотношение GFLOPS per watt на пазара в момента. В комбинация с поддръжката на HD видео ускорение, продукта може да се окаже доста привлекателен за любителите на високопроизводителни ултра компактни устройства.

Основните характеристики на чипа са:

  • Programmable DirectX 10.1 Graphics Core

The 5400E architecture includes dynamically allocated execution units for its Unified Shader 4.1 Geometry, Vertex and Pixel Shaders. DirectX 10.1 compatible Geometry-shaders allow more complex manipulation of primitives, shadows, and material effects for greater High Dynamic Range Rendering (HDR). The programmable shaders of the 5400E provide a rich user experience for Direct3D, OpenGL, OpenCL, and video rendering.

  • Vista Premium Ready

The 5400E processor is designed for Vista Premium implementations and includes support for WDDM1.0, WEI graphics that meets Vista Premium Logo requirement and AES encryption and decryption.

  • Windows 7 Ready

The 5400E processor is designed for Windows 7 implementations and includes support for WDDM1.1, WEI graphics and gaming acceleration, AES encryption and decryption and ClearType support.

  • Flexible Memory Architecture

5400E supports DDR2 memory at frequencies up to 500MHz (1.0Gbps data rate) with a maximum size of 512MB. In addition, it also supports:
256/512MB GDDR3 memory up to 850 MHz (1.7Gbps data rate)
512MB gDDR3 memory up to 800MHz (1.6Gbps data rate)
gDDR3 devices operate at 1.50V, which results in reduced power consumption when compared with GDDR3 and DDR2 devices which operate at 1.80V.

  • Advanced Power Management

Advanced power management technologies include dynamic voltage and frequency scaling and integrated temperature sensor technology. Individual execution units can also be turned-off when idle which allows additional power savings.

Advanced Display and Audio Integration
The 5400E GPU incorporates an integrated DisplayPort transmitter, two dual-link DVI transmitters, with integrated HDMI (including support for 7.1 HD audio) and HDCP, an integrated dual-channel LVDS transmitter, and legacy support for an analog CRT display.

  • ChromotionHD 2.1 Programmable Video Engine

The advanced high quality ChromotionHD 2.1 programmable video engine of the 5400E is fully compatible with Microsoft DirectX-VA 2.0 media acceleration. The engine has been optimized to provide enhanced Protected Video Playback (PVP) of a wide range of video codecs, including Windows Media VideoTM 9 HD (WMV9-HD), MPEG-2 HD, VC-1, and H.264 (MPEG-4 AVC). High definition optimized playback from Blu-ray disc is possible with lower CPU utilization. PVP support for HD Premium content includes PVP-UAB (User-Accessible Bus) and display output protection.

    То и моето вградено интелско видео GMA965 на книга беше с невероятни екстри, иначе за чеп за зеле не става.

    Никой не очаква поредният S3 Chrome да е графичен звяр ;). (IMO) За целите му на използване стига да смогва да декодира 1080p/H264 поток в реално време и да може да подкара Win7 Aero ;). Всичко останало е добро пожелание с този 64bit интерфейс на паметта :). Все пак говорим за ултракомпактни и embeded устройства където особена графична мощ не е толкова необходима.

    Ако наистина се справя с h264 във FullHD резолюция, то може и да започнат да го слагат на netbook лаптопи.
    За пример 98% от текущите netbook pc-та на пазара са с Intel GMA 950 (или 915) графични карти и липсата на алтернатива на nVidia CUDA и ATI Avivo е повече от очевадна. Абсолютно невъзможно е да възпроизвеждаш h264 в 1080p независимо от кодека, плеъра, оптимизациите, овърклока и дори ако видеото е без B-frames (което спестява ЗНАЧИТЕЛНО CPU време)
