Thanks for clarifying. After posting an earlier post, I immediately checked the Tesla SP vs. DP performance, and lo and behold SP was indeed 2x as fast as DP. Then again, this is just raw FLOPS and doesn't take into account memory movement as you say.
Not always twice the performance between SP and DP, no? I originally thought that this was the case, but looking at NVIDIA GPUs, DP is very suboptimal compared to SP. Not just half the performance.... maybe in the order of a fifth
Probably because traditional CPUs are slow w.r.t. GFLOP ratings. GPUs were designed with many stamped out vector processes, right? I wouldn't be surprised if CPUs start to advertise SP and DP in the near future with the fused CPU/GPU architectures.
They have two different FLOPS counts, one for sp, and another for dp. It's not really an apples-to-apples comparison when one FLOPS counts has 32 bits more to deal with.
AVX Instructions have a 256-bit (32 byte) wide-registers with a total of 16 registers. AVX instructions are capable of performing either single precision ordouble precision depending on the application. With the 32 byte width, one can place up to 8 floats or 4 doubles in one register.

Thanks. Both cards and both PCI-e work (I've swapped w/ only 1 running at one). I've looked for BIOS settings that will enable SLI to no avail. (There is one setting that will set if PCI/onboard will be the primary display... but has no effect).
I think I'm going to replace my...
Hi all. I've been trying to run the following config to use Visual Studio 2010 + NVIDIA Parallel NSight (dual GPU for GPU debugging):
AMD APU A3
NVIDIA Geforce 520 Ti
NVIDIA Geforce 560 Ti
Gigabyte GA-A75-UD4H mobo.
550W Antec TruePower PS
Hypothetically, my build can power both video cards...
Thank you for that insight.... I knew I was missing something so fundamental. I am going to be working in Folsom, CA as a Graphics Software Engineer... mostly validating pre-silicon chips.
Hi. Computer Engineering major here about to intern for Intel. I have to argue that architecture is the biggest thing in industry right now.
Let's start with single core processors. Before, big companies like AMD and Intel were trying to exploit performance gains from ILP (Instruction Level...
Hi all.
I just purchased the Antec ISK 300-65 Mini-ITX Case, a small form factor that has a 65W power supply.
I plan to buy a mini ITX motherboard and use a low profile Nvidia 9200 card, an optical drive, and a 250 GB mechanical SATA had drive.
Given the above configuration, I am...
