En un 3x1 que elejí entre varias sobre el tema, desde TechPowerUp, les dejo:
- Las imágenes del PCB sobre el modelo de referencia.
- La primera placa comercial de la línea, lanzada por XFX.
- Las novedades con las que cuenta la nueva línea.
Y ahora… A esperar! (Y ahorrar…:D)
Radeon HD 6870 PCB and GPU Pictured
The fine folks at IT168 revealed the first pictures of the Radeon HD 6870 PCB with its cooler completely off, and in its production livery (black). Also let out is the first [clear] picture of the GPU itself. The PCB was first pictured in its nascent qualification sample form, with a development GPU cooler on. The final version of the PCB sticks to its qualification sample for the most part, it has VRM components positioned forwards, trailed by the GPU and its memory. The card makes use of a 4+1+1 phase VRM. All eight memory chips are on the obverse side, each with its own 32-bit wide path, since there's a 256-bit memory interface.
The GPU package is of the same dimensions as the Cypress package, albeit a smaller die. We're getting to hear that Barts is pin-compatible with Cypress (meaning that a Barts GPU can be placed onto a Cypress PCB, given the appropriate BIOS, and it will work), however, no AIB is likely to reuse Cypress PCBs other than for Eyefinity6 designs, because while Barts can make do with a 6-layer PCB, close to every existing Cypress PCB is an 8-layer one, and that Cypress PCBs lack the second mini-DP connector. The die is placed diagonally on the package (à la Cypress and R600), it is rectangular, while the Cypress die is more or less square. ChipHell.com contributor musicinlove did a nice size measurement and comparison. Finally, the AMD "arrow" logo is etched onto the die, it's curtains down for ATI.
XFX Radeon HD 6870 Smiles for the Camera
XFX is ready with the first AIB-branded Radeon HD 6000 series graphics card to be caught on camera. Its Radeon HD 6870 graphics card bears a racy-looking AMD reference-design blower-type cooling solution, with its own company sticker. The company has opted for the AMD-branded Radeon logo. It draws power from two 6-pin power connectors, has no backplate on the PCB's reverse side, and sports a custom-design rear-panel on which the XFX logo is etched on the exhaust. Display connectors include two DVI, an HDMI, and two mini-DisplayPort. Radeon HD 6870 is intended to be a successor to the Radeon HD 5700 series, a performance segment product targeting a price sweet-spot. Radeon HD 5800 series successors are Radeon HD 6900 series.
AMD HD 6000 Northern Islands Feature Slides Leaked
AMD is close to unveiling its next-generation "Northern Islands" GPU family, which will be branded under the AMD Radeon HD 6000 series. These include two new performance-thru-extreme GPUs, namely Barts and Cayman. There's also a dual-Cayman implementation codenamed Antilles. While specifications are anyone's guess besides the little details we know about Barts and Cayman, the feature-set of the Northern Island family was communicated to AIB parts in a presentation which was leaked by the Chinese press.
To begin with, the key feature additions in Northern Islands includes a much more evolved display logic that can drive five displays simultaneously over physical outputs that include two dual-link DVI-I, one HDMI1.4 (full-size), and two mini DisplayPort 1.2 connectors. The logic also provides you to install up to six monitors over the two DisplayPort connectors by daisy-chaining them, making use of the MultiStream feature of DP 1.2, which supports two times the data-rate of DP 1.1, and can provide very high-resolution display, or HD display with stereoscopic 3D (120 Hz). HDMI 1.4 lets you make use of Blu-ray 3D. A new video processing engine, UVD 3.0, provides GPU acceleration for MPEG-2, DivX, MVC (multi video coding), for Blu-ray 3D.
As far as performance incentives are concerned, Northern Islands does seek to add significant performance incentives over previous generations, its also comes up with a new naming scheme. Radeon HD 6800 series will be a gamer's sweet-spot performance SKU (competitive with the lower models of NVIDIA's GeForce GTX 400 series, such as GTX 460), while Radeon HD 6900 series is purely for the entusiast, competitive with the higher-end models of the GeForce GTX 400 series, such as GTX 470 and GTX 480. A new king-of-the-hill SKU that succeeds the Radeon HD 5970 is also planned.
Some micro-technical details of the Barts-based and Cayman-based SKUs were also revealed. Barts XT and Barts Pro are slated for later this month, Cayman XT and Cayman Pro for late November, just in time for the winter shopping season. New relevant details include:
- Cayman XT and Pro SKUs will feature 1 GB of GDDR5 memory
- Cayman XT will make use of new 6 Gb/s GDDR5 chips, likely to increase memory bandwidth by 20%; Cayman Pro will also see a 20% increase in memory bandwidth, over previous generation
