AMD's recent introduction of the Radeon HD 4800 series has impressed many people, from reviewers to purchasers, and some have lauded the cards as AMD/ATI's return to the market. That would definitely be a boon to AMD given that both their GPU and CPU markets have suffered since around the time of the AMD/ATI acquisition.

According to recent speculation, AMD might be able to capture up to 40% of the discrete market by the end of 3rd Quarter of 2008. The reasons are pretty plain, with the HD 4800 cards not only delivering on performance promises but also coming in at a very nice price point. Time will tell, and though this is only speculation, it's a real possibility that would benefit us. Many were disappointed by the 9000 series GeForce cards, and the newest Nvidia offerings are rarely friendly on the wallet – some healthy competition is due.

ATI which merged with AMD 2 years back has recently launced their Radeon R700 series graphic card. The R700 follows a naming convention of 4XXX, a list of R700 graphic cards can be found here.
The two latest cards HD 4850 and HD 4870 offers a very high performance with a competitive price. The 4850 matches and often beats the performance of 9800 GTX while the 4870 matches that of GTX 280 with much lower prices.

For the next few months, the big battleground is likely to be in notebook computer platforms, where both companies have new offerings, many of which are being rolled out at this week’s Computex show in Taiwan. AMD today formally introduced its new notebook platform, which has been referred to under the code-name of Puma, though officially it’s just the next generation notebook platform. The CPU is the Turion X2 Ultra chip (formerly code-named “Griffin”), which basically is two K8 cores (the same cores used in the Athlon processors) with some interesting new features: independent dynamic cores let the chip set different power levels for each core and the integrated “north bridge” chip, power optimized HyperTransport 3; a a mobile-optimized memory controller designed for DDR-800 memory.

The heart of the platform is the new 7-series chipset with support for the ATI Mobility Radeon 3000 family of graphics and Wi-Fi support from a third-party chipset (such as Atheros, Broadcom, or Marvell). The graphics come in several flavors. Most distinctive is the HD 3000 integrated graphics solution, which includes support for Avivo HD (for better hardware-assistend HD decode). AMD believes this will far outperform Intel’s integrated graphics. AMD says this solution will offer three times the 3D performance, 5 times the HD quality, and 40% faster wireless than Intel’s solution. I’m a bit skeptical on some of these numbers, but the proof will be in the final notebooks.
