Jon Peddie Research (JPR) has published its third quarter statistics for the graphics processor market showing weak seasonal performance with shipments down 1.45% quarter-over-quarter and 10.8% year-over-year. The underwhelming results were largely blamed rocky PC shipments, which stems from factors including ongoing economic woes in the US and abroad as well as the increasing popularity of tablets.
Discrete graphics shipments hit 34.3 million units, up 4.5% on-quarter, down 5.2% on-year and trending up with a CAGR of 2.6% by 2016. Of the three major graphics chip manufacturers, Nvidia made out the best with a quarterly increase in discrete desktop shipments of 28.3% as well as a 12% jump in discrete mobile shipments and an overall increase in PC graphics shipments of 19.6% (though it's down 0.5% on-year).
AMD and Intel fared much worse. AMD's quarterly PC graphics shipments fell 10.7% (20% on-year), which includes a 30% decline in desktop APUs (CPUs with an integrated GPU) and a 4.7% drop in notebook APUs. Meanwhile, Intel's quarter-over-quarter shipments of desktop CPUs with integrated graphics fell 7%, notebook chips with IGPs fell dropped 8.6% and overall PC graphics shipments slipped 8%.
Share-wise, Nvidia is still in third place with 18.5% (22.25 million units shipped), up 3.7% on-quarter, AMD stands at 21.2% (25.43 million units moved), down 1.5%, and Intel holds 59.8% (71.75 million units shipped), down 2.4%. The remaining sliver of share is split between VIA/S3 and Matrox, the former of which holds 0.4% of the market and the latter has 0.03% with less than one million units shipped combined.
The Nvidia GeForce GTX 680 contains four GPCs with a total of eight SMXs, 1536 CUDA cores, eight geometry units, four raster units, 128 texture units, and 32 ROP units. The base clock is 1006MHz, the GTX 680 also carries 2GB of GDDR5 VRAM running at 6008MHz with a 256-bit interface providing 6.0Gb/s of throughput. Dual six-pin power connectors feed the card's TDP of 195W.
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.
The HD 7950 has 2048 SPUs, 128 TAUs and 32 ROPs. The only other ports are on the I/O panel where you'll find a dual DL-DVI connector, a single HDMI 1.4a port, and two mini-DisplayPort 1.2 sockets. Supports a max resolution of 2560x1600 on up to 3 monitors.
