Nvidia has launched a pair of GPUs that the chip giant claims are four times faster than last year's offering.

The Pascal architecture is continuing to find its way through Nvidia's product line-up, with today marking the introduction of its Tesla P4 and P40 GPUs.

According to Nvidia's specs sheet, the P40 clocks in at 12 teraflops for single precision calculation and 47 trillion int8 operations per second thanks to 24GB GDDR5 memory with 346GBps bandwidth, and 3,840 CUDA cores. The less powerful P4 offers 5.5 teraflops for single precision and 22 trillion int8 operations per second, backed by 2,560 CUDA cores and 8GB GDDR5 memory with bandwidth of 192GBps.

Designed for artificial intelligence and running neural networks, the P40 will be available next month, while the P4 will arrive in November.

The company said the chips offer four times the performance of its M40 and M4 launched last year. Compared to using an Intel Xeon E5-2690v4, which was launched earlier this year, Nvidia claimed its offering is 40 times more power efficient while being 45 times faster to respond.

"A single server with a single Tesla P4 replaces 13 CPU-only servers for video inferencing workloads, delivering over 8x savings in total cost of ownership, including server and power costs," the company boasted...
