Munich, May 21, 2008 - Qimonda AG, a leading manufacturer of memory products, today announced that the company has won AMD as launch partner for the new graphics standard GDDR5. Qimonda already started mass production and the volume shipping of GDDR5 512Mbit components with a speed of 4.0Gbps to AMD, a leading global provider of innovative processing solutions in the computing, graphics and consumer electronics markets.
GDDR5 will become the next predominant graphics DRAM standard with a tremendous memory bandwidth improvement and a multitude of advanced power saving features. It targets a variety of applications, starting with high performance desktop graphic cards followed by notebook graphics. Later on also the introduction in game consoles and other graphics intensive applications is planned. "We are very proud to supply AMD with GDDR5 volume shipments only six months after first product samples have been delivered," said Robert Feurle, Vice President Business Unit Specialty DRAM of Qimonda AG. "This is a further milestone in our successful GDDR5 roadmap and underlines our predominant position as innovator and leader in the graphics DRAM market." "Qimonda's strong GDDR5 roadmap convinced us to choose them as a primary technology partner for our GDDR5 GPU launch," said Joe Macri, Sr. Director, Circuit Technologies, AMD. "Both the early availability of first samples and volume shipments added great value to the development and launch of our upcoming high-performance GPU." http://www.vr-zone.com/articles/Qimo...hics/5789.html

R870 is 40nm with 2000sp? We heard from chiphell forum that TSMC now tries 40nm process to produce ATI RV740 graphics chip in the labs. It’s said that RV740 would be the vanguard of 40 nm graphics chips. We heard 40nm RV740 would be announced at the end of this year. Also at the first half of 2009, ATI would introduce R870, the last graphics chip based on R600 architecture. R870 would be 40nm chip with 2000 sp inside. http://www.pczilla.net/en/post/16.html

che rv740, quindi fascia mainstream quindi le 46x0, e anche rv710 quindi le 44x0 possano essere a 40-45nm era quasi scontato visto che ati da sempre ha realizzato le schede di fascia media e bassa con tecnologia "meno affinata" a livello di accortezze ma con un livello di produzione e costo minore. r870 boh siamo davvero in campo rumors insomma si parlerebbe dell'ultima incarnazione dell'archidettura base di r600, e cmq si parla della vga che sarà presentata a giugno 2009, contanto se mantiene l'archidettura superscalare di ati dovrebbe avere un numero di 400 cluster superscalari... e insomma passare dai 64 di r600 rv670 ai 96 di rv770 ai 400 di r870 mi pare un pò tanto...cmq vedremo...intanto godiamoci sto rv770... riguardo invece alla hd4850 con gddr4, ufficialmente sarà anche stata cancellata ma credo che i vendor come sapphire sicuramente ne presenteranno un modello con gddr5

Aumentando la frequenza di core/shaders (4870) le ddr5 danno un buon boost. |

L'unica cosa che differenzia la 4850 dalla 4870 sono le frequenze...

Sarà quindi probabile un refresh in un secondo momento di RV770 a 40nm?
Forse per limitare ancora di più i consumi e per consolidare definitivamente la produzione a 40nm?

Lì si dice non che il boost prestazionale da GDDR3 (2000MHz) a GDDR5 (3900MHz) è piccolo, ma che la differenza tra una HD4850 GDDR5 e una HD4870 GDDR5 era piccola, e rischiavano di pestarsi i piedi.

AMD (NYSE:AMD - News) today announced the first commercial implementation of Graphics Double Data Rate, version 5 (GDDR5) memory in its forthcoming next generation of ATI Radeon™ graphics card products. The high-speed, high-bandwidth GDDR5 technology is expected to become the new memory standard in the industry, and that same performance and bandwidth is a key enabler of The Ultimate Visual Experience™, unlocking new GPU capabilities. AMD is working with a number of leading memory providers, including Samsung, Hynix and Qimonda, to bring GDDR5 to market.
Today’s GPU performance is limited by the rate at which data can be moved on and off the graphics chip, which in turn is limited by the memory interface width and die size. The higher data rates supported by GDDR5 – up to 5x that of GDDR3 and 4x that of GDDR4 – enable more bandwidth over a narrower memory interface, which can translate into superior performance delivered from smaller, more cost-effective chips.1 AMD’s senior engineers worked closely with industry standards body JEDEC in developing the new memory technology and defining the GDDR5 spec. “The days of monolithic mega-chips are gone. Being first to market with GDDR in our next-generation architecture, AMD is able to deliver incredible performance using more cost-effective GPUs,” said Rick Bergman, Senior Vice President and General Manager, Graphics Product Group, AMD. “AMD believes that GDDR5 is the optimal way to drive performance gains while being mindful of power consumption. We’re excited about the potential GDDR5 brings to the table for innovative game development and even more exciting game play.” The introduction of GDDR5-based GPU offerings marks the continued tradition of technology leadership in graphics for AMD. Most recently, AMD has been first to bring a unified shader architecture to market, the first to support Microsoft DirectX® 10.1 gaming, first to lower process nodes like 55nm, the first with integrated HDMI with audio, and the first with double-precision floating point calculation support. AMD expects that PC graphics will benefit from the increase in memory bandwidth for a variety of intensive applications. PC gamers will have the potential to play at high resolutions and image quality settings, with superb overall gaming performance. PC applications will have the potential to benefit from fast load times, with superior responsiveness and multi-tasking. “Qimonda has worked closely with AMD to ensure that GDDR5 is available in volume to best support AMD’s next-generation graphics products,” said Thomas Seifert, Chief Operating Officer of Qimonda AG. “Qimonda’s ability to quickly ramp production is a further milestone in our successful GDDR5 roadmap and underlines our predominant position as innovator and leader in the graphics DRAM market.” GDDR5 for Stream Processing In addition to the potential for improved gaming and PC application performance, GDDR5 also holds a number of benefits for stream processing, where GPUs are applied to address complex, massively parallel calculations. Such calculations are prevalent in high-performance computing, financial and academic segments among others. AMD expects that the increased bandwidth of GDDR5 will greatly benefit certain classes of stream computations. New error detection mechanisms in GDDR5 can also help increase the accuracy of calculations by indentifying errors and re-issuing commands to get valid data. This capability is a level of reliability not available with other GDDR-based memory solutions today. http://forums.vr-zone.com/showthread.php?t=278539

Se invece la banda aumenta del 70%, allora il discorso diventa differente.

Nonostante abbia una simpatia maggiore per ATI, devo dire che hai proprio ragione.
Fare innovazione è senz'altro un pregio, ma poi bisogna anche mettere dietro la concorrenza,altrimenti è stupido comprare prodotti innovativi,che però vanno meno di quelli "vecchi". Non per niente Nvidia si è presa molto mercato con gli ultimi prodotti commercializzati....

Secondo me non basta l'innovazione , ma occorre anche avere la forza per imporla..:gli ultimo game di rilievo a cui ho giocato erano tutti parte del programma supporto game NVIDIA...
Insomma , voglio dire che si può innovare quanto si vuole ma senza dare un supporto adeguato (alias denaro) affinchè le software house scrivano codice in grado di esaltare la propria architettura hardware..tutto è inutile... Imho , anche questo è stato un forte limite di R600. |
