It wasn't unusual for AMD to be the only company to deploy HBM; AMD and Nvidia had split similarly over the use of GDDR4
a decade ago, with AMD adopting the technology and Nvidia choosing to stick with GDDR3.
(10) In addition to the caps on royalties for its SDR and DDR DRAM technologies, Rambus's commitment to the EC also caps royalty rates for, among other things, DDR2, DDR3, GDDR3, and GDDR4
SDRAMs and memory controllers.
Under this agreement Rambus has granted NVIDIA a patent licence for certain memory controllers at a 1% royalty rate for SDR memory controllers and a 2% royalty rate for other memory controllers, including DDR, DDR2, DDR3, LPDDR, LPDDR2, GDDR2, GDDR3, GDDR4
and portions of GDDR5 memory controllers.
The system offers maximum test speeds of 3.2 Gb/s and also can test GDDR3 and GDDR4
The ATI Mobility Radeon HD 4800 series graphics processors are the industry's first to support GDDR5 memory technology, providing nearly twice the memory bandwidth of GDDR3 and GDDR4
, contributing to improvements in game play and performance.
The GPU runs at a clock speed of 650MHz and also offers 48-pixel shaders and eight vertex shaders, responsible for adding textures and effects to graphics.ATi's standard specifications for X1950 XTX cards recommend the 512Mbytes of GDDR4
memory run at 1GHz.
AMD was the only company to make significant use of GDDR4
or HBM, after all.
The memory tester offers maximum test speeds of 3.2 Gb/s and data transmission speeds of > 1 Gb/s and can test GDDR3 and GDDR4
in addition to DDR3-SDRAM.

Steeply tapered edges and lights embedded around the chassis make for one of the most eye-catching models out there, and with 4GB of GDDR4
RAM and 16GB of main memory, there's enough grunt under the hood to take on today's most demanding games.
