Trident XP4 desktop GPU family — officially

Today Trident Microsystems officially announced its family of DX8.1 / 9.0 XP4 GPU with tile architecture for up to $100 graphics cards supporting up to 128MB and up to 700 MHz (DDR) clock rates.

XP4 desktop family includes:

  • XP4 T3 — up to 128MB of 128-bit up to 700 MHz DDR memory
  • XP4 T2 — up to 64MB of 128-bit up to 500 MHz DDR memory
  • XP4 T1 — up to 64MB of 128-bit up to 500 MHz DDR memory

As for DX8.1/9.0 cards below $100, they mean the most performance XP4 T3 chip with 300 MHz clock rate and less than 4 W dissipated power.

XP4 T2 operates at 250 MHz. According to the company, 64MB cards will appear in retail for less than $79.

Low-end XP4 T1 250 MHz cards will cost less than $69.

All XP4 family GPUs are made at UMC facilities using 0.13-micron CMOS process technology and feature about 30 million transistors. The company name the following main advantages of XP4 chips:

  • BrightPixel rendering engine with hardware vertex and pixel shaders
  • SmartTile memory architecture with throughput optimization
  • CoolPower energy saving technology
  • Multiview supporting CRT, DVI and TV out
  • Up to QXGA (2048x1536) resolutions with 420 MHz RAMDAC
  • DXVA with IDCT and Motion Compensation hardware support
  • Modern deinterlacing technology for high-quality DVD playback
  • AGP 4

All three XP4 desktop models are packaged into 612-pin BGA (31x31 mm) casings. Currently XP4 T1, T2 and T3 are available as samples only, their volume production is expected in October. Presumably, Trident Microsystems will follow NVIDIA and will only ship its GPUs to third party card makers. Up to 90% of shipments are expected to be T2 and T1 models. According to the company, XP4 T3 core can be a rival to GeForce4 Ti 4200 and Radeon 9000 Pro. But let´s be sceptic before first test results arrive.
