Que Bonita Familia 2: Proximos Radeon HD7000
Que barbaridad, apenas me hago de una Radeon HD6870 para suplir la vuierja HD4850 y sale que en este año AMD sacara los primeros modelos de la nueva familia Radeon HD7000.
Nueva tecnologia nuevo fabricante del semiconductor, otar cosa interesante es que poco a poco AMD esdta relegando su propia compañia y rama Global Foundries de para pasar a usar compañias externas, algo curioso ya que AMD precisamente compro y fundo para no depender de otros en el diseño y fabricacion de los chips. De esta forma es que nuevamente contrata a Taiwan Semiconductor Manufacturing Co. Ltd. (Hsinchu, Taiwan) para la fabricacion del GPU. Ya antes en la fabricacion de los APUs -CPU+GPU o CGPU- Llano de los cuales ya hablamos.
Como sea, estaran usando estos nuevos Radeon tecnologia de 28nm, con lo que el HD7790 tendra el doble o poco mas que un HD6770 actual y con menor consumo y generacion de calor. Imaginen el poder de computo de la sigueinte generacion de APUs hechos con estos GPUs HD7000. Estos modelos ya estaran usando la nueva version del bus de datos PCIE v3.0
Y estas serian las posibles caracteristicas tecnicas a confirmar:
- HD 7990 New Zealand GCN
- HD 7970 Tahiti XT GCN 1000MHz 32CUs 2048ALUs 128TMUs 64ROPs 256bit X.DR2 8.0Gbps 256GB/s 2GB 190W HP
- HD 7950 Tahiti Pro GCN 900MHz 30CUs 1920ALUs 120TMUs 64ROPs 256bit X.DR2 7.2Gbps 230GB/s 2GB 150W HP
- HD 7870 Thames XT VLIW4 950MHz 24SIMDs 1536ALUs 96TMUs 32ROPs 256bit GDDR5 5.8Gbps 186GB/s 2GB 120W HPL
- HD 7850 Thames Pro VLIW4 850MHz 22SIMDs 1408ALUs 88TMUs 32ROPs 256bit GDDR5 5.2Gbps 166GB/s 2GB 90W HPL
- HD 7670 Lombok XT VLIW4 900MHz 12SIMDs 768ALUs 48TMUs 16ROPs 128bit GDDR5 5.0Gbps 80GB/s 1GB 60W HPL
- HD 7570 Lombok Pro VLIW4 750MHz 12SIMDs 768ALUs 48TMUs 16ROPs 128bit GDDR5 4.0Gbps 64GB/s 1GB 50W HPL
Su salida se rumora seria para septiembre-noviembre del 2011.

Radeon HD 7000-series
AMD is reportedly already preparing its next series of Radeon HD 7000-series GPUs, and planning to start mass production of the new chips in May this year.
Taiwanese tech site DigiTimes claims the move will follow the introduction of the company's Radeon HD 6670, 6570 and 6450 GPUs this month, citing graphics card makers as its source.
There's no word on the specifications of the new GPUs yet, but previous rumours have stated that they will be fabricated using TSMC's 28nm facilities.
We originally expected to see new GPUs based on TSMC’s 28nm manufacturing process in autumn this year, and the smaller transistors will represent a large step down the process scale from the current 40nm process used for AMD’s Radeon HD 6000-series and Nvidia’s latest GeForce 500-series GPUs.
The usual benefits of a process shrink are higher frequencies and more space for resources in the die. This can all be squeezed into a piece of silicon that’s the same size as the previous comparative GPU, so costs per comparable GPU (or card) usually remain similar.
Previous rumours have suggested that the new range of GPU, codenamed Southern Islands, will be based on the same architecture found in AMD's current Cayman-architecture chips, such as the Radeon HD 6900-series. This seems sensible, given AMD's claims that the VLIW4 stream processor architecture of Cayman is more efficient per mm2 of silicon than the VLIW5 design of its previous GPUs.
However, while we’d expect some upgrades in other areas of the GPU design to complement the stream processor design, it looks as though we shouldn't expect anything as radical as the original Nvidia Fermi design, which broke up the front-end of the GPU and distributed various elements throughout the design.
There may still be room for adding new stream processors to the GPU, though, especially if AMD does indeed deploy a 28nm process. There are no figures yet, of course, but given the huge process-shrink, a doubling of the stream processor count seems a conservative estimate. This could potentially result in the fastest GPUs featuring over 3,000 stream processors.
Are you excited by the rumours about the Radeon HD 7000-series, or are you going to wait until you see the reviews here before making a judgement? Let us know in the forums.
Un poco de los nuevos APUs que vendrian

AMD's Trinity GPU Officially Branded as Radeon HD 7000
It's not a surprise, but nevertheless: AMD's next APU will feature a GPU branded the AMD Radeon HD 7000 series, as indicated by a GlobalFoundries slide shown in a presentation today.
The slide specifically references the upcoming Trinity APUs, 32nm parts that are slated to replace current Llano A-series APUs when they're released in 2012. AMD says that Trinity APUs should outperform Llano APUs by about 50 percent (at least, when measured in teraflops).
Like the existing Radeon HD 6000 series, the 7000 series will eventually include both on-board APU graphics and more traditional dedicated graphics cards - these dedicated GPUs are currently codenamed Southern Islands, and are expected to be manufactured on a 28nm process.

Como ven el mercado de computadoras portatiles y de maquinas de gama baja se veran muy beneficiadas en rendimiento y gasto energetico de estos chips con nuevas tecnologias en el proceso de fabricacion, teniendo equipos mas potentes, mas pequeños y mas ecologicos.
