Following on from last week's report covering the entire graphics market, where Intel came on top thanks to its integrated offerings, JPR has released new market share figures related strictly to discrete add-in board (AIB) GPU shipments and sales during Q4 2011. The report takes into consideration graphics cards used in desktop PCs, workstations, and servers, that are either factory installed or sold directly to consumers.
According to the market research firm, overall discrete graphics cards shipments shrank from 17.2 million in the third quarter of 2011 to 16.1 million in the fourth, a 6.5% drop. Shipments during Q4 2011 behaved according to past years' seasonality but were lower on a year-to-year basis. In terms of sales the AIB market reached $14.9 billion, down 0.4% from 2010 due to a pull back by consumers and a decline in average selling prices.

As usual, it was a two horse race between AMD and Nvidia. The latter saw graphics cards shipments increase by 3.7% from Q3 2011 to 63.4% while AMD-based boards decreased 3.6% to 36.3% for the same period. On a year-to-year basis AMD lost market share by 2.7% while Nvidia gained 2.9%.
While the graphics card market seems to be gradually shrinking as system-on-chip and other integrated graphics solutions get more powerful, JPR notes that longstanding predictions about the death of add-in boards are greatly exaggerated, pointing out that overall graphics chips shipments are down 10.4% for the quarter whereas AIBs only declined 6.5% sequentially in a seasonally down quarter.
The NVIDIA GeForce GTX 560 Ti 1GB boasts 384 CUDA cores, there are also 64 TAU (Texture Addressing Units) units. Breaking it down, we have 2 Graphics Processing Clusters, 8 Streaming Multiprocessors, 384 CUDA Cores, 64 Texture Units and 32 Raster Operations Units. The GeForce GTX 560 Ti is paired with 1024MB of GDDR5 memory clocked at 1002MHz (4008MHz DDR). Combine that with a memory interface of 256-bit and you get a peak theoretical bandwidth of 128GB/s.
The AMD ATI Radeon HD 7970 measures 27 cm long (10.6 in), the GPU core is clocked at 925MHz, and the GDDR5 memory operates at the same frequency of 1375MHz (5.5GHz DDR). Still, pairing that frequency with a 384-bit memory bus gives the HD 7970 264GB/s of theoretical bandwidth. The HD 7970 carries 2048 SPUs, 128 TAUs and 32 ROPs, up 33% from 1536 SPUs and 96 TAUs, it's also the first PCI Express 3.0-compatible card.
