Qimonda Samples GDDR5

Memory manufacturer Qimonda claims to have started producing the worlds first 512MB GDDR5 chips. Like past GDDR revisions, GDDR5 increases the maximum bandwidth between a graphics processor and the graphics memory. GDDR5 boasts a whopping 20GB/s bandwidth, up from the GDDR4 bandwidth of 16GB/s. Qimonda claims that GDDR5 improves power consumption by downclocking unused VRAM. Qimonda will release their GDDR5 RAM "sometime in 2008". You can read the full Qimonda GDDR5 briefing here.

Se é a empresa que trabalhas, parece que tas surpreso com esta noticia :D já se sabia ha muito que a Quimonda ia saltar de Gddr3 para Gddr5.

ja tinha ouvido falar, mas falar é uma coisa fazer é outra!!!!
existem mt dificuldades nesse tipo de produçao... e se isso for avante vao ser produzidas em portugal!!!!!!!

Don't Get Too Accustomed to GDDR4: Qimonda Ships GDDR5 SGRAM

Qomonda ships the first samples of GDDR5 SGRAM memory

Global memory supplier Qimonda today announced that it is has shipped the industry’s first 512MB Graphics Double Data Rate (GDDR5) samples to partners and customers. GDDR5 SGRAM is the successor to GDDR4 SDRAM, which has yet to completely overtake GDDR3 SDRAM.

The Joint Electron Device Engineering Council (JEDEC) has not solidified the standards for GDDR5. However, JEDEC's GDDR5 special interest group is in its second year of operation, and finalized specifications may come sooner than later.

GDDR5 features data rates at 20GByte/s per component. This is double the bandwidth of the fastest GDDR3 memory.

GDDR5 operates using two different clock types. One clock type that GDDR5 comes with is a differential clock (CK), where address and command inputs are referenced. The other clock type that GDDR5 uses is the forwarded differential write clock (WCK), which operates at twice the frequency of the CK. Read and write data are referenced to the WCK.

Each write clock of GDDR5 SGRAM is assigned to two bytes.

The CK and WCK signals are aligned during the initialization and training sequence. The use of two separate clocks allows for minimal noise and jitter at high data rates

In addition to larger bandwidth and faster speeds, GDDR5 also comes with new power saving features that previous GDDR memory versions don't have. GDDR5 SGRAM has been designed in a way to consume power only when it is really needed.
The DRAM core of GDDR5 features various integrated low power modes. In addition, GDDR5 also allows the system to dynamically scale its I/O data rate depending on the workload at hand. I/O data rate can be changed from 5 Gbps all the way down to 200 Mbps,

JEDEC analysts estimate initial GDDR5-equipped products will appear in late 2008 on very select applications. High end graphics cores in development today, NVIDIA's next-generation architecture and AMD's R700, would be the first graphics cores capable of utilizing the new signalling required for GDDR5.

However, the dynamic power management and frequency scaling make GDDR5 most useful for mobile applications. Given the slower release schedules of mobile hardware, GDDR5 will not make a splash into the notebook market until 2009.

In addition to desktop and notebook graphics, GDDR5 is also expected to be used in game consoles and other graphics intensive applications.

Isto da informatica.. é do melhor LOL
 
Espectáculo, realmente como o Romani48 diz "Informática no seu melhor...".

Eu por mim era altura de estabilizar, mas estas companhias querem sempre forçar o "para á frente é o caminho".
 
pois.. esqueçam a antiga designação Next GEN.. isto é next gen.. e penso que isto poderá beneficiar o surgimento do DX11, pois mais shaders = + consumo e velocidade de memoria requerida
 
ai estao elas da Hynix e são de 1Gb


Hynix Introduces Industry's First 1Gb GDDR5 DRAM

Hynix Semiconductor today introduced the industry’s first 1 Gigabit GDDR5 Graphics DRAM. The industry’s first 1Gb GDDR5 from Hynix is also the fastest and highest density graphics memory available. It operates at 5Gbps bandwidth and processes up to 20 Gigabytes of data per second with a 32-bit I/O, ideal in applications with high definition video and cinematic and photo-realistic graphics content. A bandwidth of 20 Gigabytes per second offered by the Hynix 1Gb GDDR5 can process more than 20 hours of DVD quality video.




The newly introduced GDDR5 is built on the company’s leading edge 66nanometer process technology and designed to minimize power consumption. In addition to its small form factor and power saving characteristics, Hynix’s GDDR5 features time delay adjustments, error correction and jitter control technology enabling more robust system designs.

The fifth generation graphics memory GDDR5 improves data processing speed by more than two times than that of GDDR3, the current mainstream graphics DRAM device. With its improved speed and power characteristics, GDDR5 is projected to succeed GDDR3 and dominate the graphics DRAM market from the 2nd half of 2008.

Hynix plans to start mass production of GDDR5 in the first half of next year to meet the increasing demand for high performance graphics DRAM.

1Gb. (Gigabit) = menos de 128 Megabytes por chip.

E não estão aí nada.
Se a "mass-production" só começa a meio de 2008, não esperes ver produtos com ela senão daqui a um ano (numa perspectiva extremamente optimista...).
 
Última edição pelo moderador:
A Samsung afirma ter inventado a memória gráfica mais rápida do mercado, capaz de transferir dados a 6GB/seg.

Segundo a empresa, a série cinco com chips GDDR5 (graphics double-data-rate) é quatro vezes mais rápida do que os chips que podemos encontrar instalados hoje nas consolas.

Os chips vão ser introduzidos no mercado com uma densidade de 512MB (16MBx32). A Samsung acredita que o o GDDR5 vai estar instalado em metade dos computadores de topo já em 2010.

A Samsung não é o primeiro fabricante a apresentar o GDDR5 ao mercado. A Hynix já anunciou chip de 1GB GDDR5 e a Quimonda já confirmou ter chips no mercado no ínicio de 2008.
