A lot has been said about NVIDIA's upcoming product with which it will compete against AMD's Radeon HD 7900 series, except of course, pictures, benchmarks, and so on. Chinese tech forum ChipHell accused NVIDIA of deploying shills across forums to shape public opinion about the already-launched HD 7900 series, towards waiting for NVIDIA's competitive product, these include blind talk about imaginary performance superiority, killer price, etc.

Chinese forums have recognized patterns in this spurt of anti-AMD and pro-HD 7970 imaginary-competitor product posts and banned scores of user accounts engaged in this activity. There's a very potent reason why ChipHell's observations shouldn't be met with cynicism, or made light of. In China, competing factions in the ever-ruling Communist party have been known to use what is known as "the 50 cent army", where for a pittance, scores of internet forum posters can be engaged to perform coordinated PsyOps, to shape public opinion, and maintain public support. It is only natural, then, that competing companies in the extremely competitive Chinese domestic market resort to similar tactics, including those distributing NVIDIA GeForce graphics cards, or, as Chip Hell alleges, NVIDIA itself.

This month-end, AMD will launch the second product in its high-end Radeon HD 7900 series, the HD 7950, which is based on the same "Tahiti" silicon as the HD 7970, but with a few components disabled. Reliable sources revealed to DonanimHaber the reference clock speeds of the HD 7950. The core of the HD 7950 will be clocked at 800 MHz, and the memory at 1250 MHz (actual), 5.00 GHz (GDDR5 effective). This, compared to the 925 MHz (core), 1375 MHz (memory actual)/ 5.50 GHz (memory effective) clock speeds of the HD 7970. The HD 7950 will hence be a good overclocker considering the speeds it comes with, there is scope for quite a few factory-OC models from AIBs. In related news, DonanimHaber notes that the HD 7950 on average will be US $100-150 cheaper than the HD 7970 (US $400-$450).

AMD Radeon HD 7970 launch is just around the corner. Ahead of its launch, AMD conducted its usual press briefing. DonanimHaber has access to some of the slides shown in that meeting. Earlier this day, we brought you perhaps the most important of them all, specifications. Let's take a look at the reference board design itself. AMD is sticking to the black+red colour scheme, and has come up with a swanky new cooling assembly design. The design, unlike those of higher-end Radeon HD 6000 series graphics cards, is surprisingly curvy and features dashes of red plastic making up its contours, surrounded by tougher black ABS.

A welcome change here from the previous generations, is that the card is truly single-slot capable, when say, a single-slot full-coverage water block is used. High-end cards from previous generation HD 5000 and HD 6000 have a dual DVI connector cluster that extends into two expansion slots, which many enthusiasts found to be annoying, especially when setting up benches with four single-GPU graphics cards in scenarios where PCI-Express slot spacing isn't kind. Moving on to display connectivity, the card has one DVI, one HDMI, and two mini-DisplayPort connectors, all arranged in the confines of a single expansion slot. The space of the second slot is dedicated to a hot-air exhaust of the cooling assembly. All board partners are required to ship HDMI-to-DVI dongles, and active mini-DP dongles.

AMD CEO Rory Read, speaking at the IT Supply Chain conference organized by Raymond James this Tuesday, said that his company had begun shipping 28 nm GPUs for revenue (meaning, in volumes big enough to fetch revenue). With it, AMD fulfilled its promise to be the first to the market with GPUs built on the 28 nm silicon fab process. AMD's foundry partner for these chips is TSMC. "We are ramping 28nm [products] with TSMC in Taiwan and shipping the products here and now. We are very excited about the products," said Read.

At the upcoming CES event, AMD will formally unveil a range of products that will use its 28 nm GPUs. CES will give AMD a good opportunity to bag design wins with large volume manufacturers of notebooks and PCs. What this means for the enthusiast community is that whenever AMD does launch its Radeon HD 7900 series, it won't be a "paper-launch".

Reliable sources among AMD add-in board partners told DonanimHaber that the upcoming AMD Radeon HD 7900 series will introduce a new feature that other SKUs based on Southern Islands GPUs could also include. It's called Eyefinity 3D, and as the name might suggest, it's the next major update to Eyefinity, a technology that lets you span a single display head across up to six physical displays, and gives you the ability to use your available physical displays to accommodate multiple such display heads.

Eyefinity 3D adds support for 3D-optimized (120 Hz) displays, and lets you create large stereoscopic 3D display heads using a number of physical 3D displays. The technology behind this might not be as simple as it sounds, because the driver has to take into account the viewing angles of the displays in perspective to the user (as entered by the user), and calibrate the 3D image output. The same sources also hinted about the pricing of Radeon HD 7970.

AMD today released its latest unofficial drivers, Catalyst 12.1 Preview. Surprisingly, this release comes ahead of the month's scheduled WHQL-signed release, Catalyst 11.12 WHQL. According to sources, 12.1 Preview is the first driver that provides early (read: rough-on-the-edges) support for AMD's next generation Radeon HD 7900 series graphics cards, scheduled for launch on the 9th of January, 2012. That apart, Catalyst 12.1 brings the following changes to the table:

• AMD HD3D technology support enhancement
  o Enables support for AMD HD3D technology in conjunction with AMD CrossFireX configurations
  o Delivers a new Stereo 3D mode over HDMI 1.4a connections - 1080p at 30Hz is now enabled on supported displays.
• AMD Catalyst Control Center / Vision Engine Control Center enhancements - Application Profiles
  o AMD Catalyst 12.1 Preview driver enables users to create per application profiles to individually control 3D and CrossFireX settings for Direct3D applications
  o Please be sure to select the "Restore Factory Defaults" option under the Catalyst
• Control Center Preferences menu before using the new application profiles feature - this ensures there are no compatibility issues between previous drivers and the new AMD Catalyst 12.1 Preview driver with regards to application profiles
• AMD Catalyst Control Center / Vision Engine Control Center enhancements - Video UI improvements
  o AMD Catalyst 12.1 Preview driver includes user interface enhancements to simply adjustment of video color and video quality controls
• Performance highlights of the AMD Catalyst 12.1 Preview driver (in addition to the AMD Catalyst 11.11c performance driver)
  o Improves performance (10%) in Elder Scrolls: Skyrim when Multi-Sample Anti-Aliasing is enabled on the AMD Radeon HD 6900 Series for single GPU and AMD CrossFireX configurations

Ladies and Gentlemen with graphics card upgrade plans, circle the date January 09, 2012, for this is going to be the day AMD will launch its next generation high-performance graphics cards in the Radeon HD 7900 series, according to reliable market sources DonanimHaber spoke with. On the 9th, AMD is expected to unveil at least two new SKUs in the HD 7900 series, most likely, HD 7970 and HD 7950. These will be based on the new 28 nm "Tahiti" silicon that will use completely redesigned number-crunching machinery, and a very wide memory bus.

AMD is on course to releasing its latest "Southern Islands" GPU family, and a fleet of desktop graphics card SKUs based on it, which will be led by a new high-performance GPU, codenamed "Tahiti", which will make up Radeon HD 7900 series; followed by performance GPU "Pitcairn", on which HD 7800 series will be based; "Thames" and "Lombok" making up the rest of the lineup. According to a report by DonanimHaber, HD 7970 (working name) is expected to be competitive with (or outperform) GeForce GTX 580, and priced at US $499. The HD 7950 will be competitive with (again, or outperform) GeForce GTX 570, being priced at US $399.

Things get interesting with Pitcairn, which is the successor of "Barts". This performance GPU is designed for sweet-spot SKUs, such as HD 7870 and HD 7850, which will be competitive with GeForce GTX 560 Ti / GTX 560, and priced at US $299 and $199, respectively. The Radeon HD 7670 will be particularly expensive, priced at US $179, followed by HD 7650 at $119. Further, it was reported that HD 7970 and HD 7950 will have a standard memory size of 3 GB.

Following our article yesterday about AMD using new high performance liquid cooling technology for their upcoming 7900-series graphic cards, TechPowerUp can now bring you a detailed insight into how this technology works, which has been developed by Vapro Inc. The following slides will help to explain this technology.

By using liquid cooling based heatsinks, the following performance advantages are achieved: improvement of thermal resistance, handling of high heat flux and power and easy to manufacture.
