M20x0 PCI Cards for accelerator blade bullx B505
The Tesla M-class GPU modules are integrated into bullx B505 servers.
M20x0 PCI cards
The bullx blade B505 contains two NVIDIA® Tesla™ graphics processing unit (GPU) PCI cards.
The NVIDIA® Tesla™ M20-Series graphics processing unit (GPU) Computing Module is a PCI Express, double-wide, full-height (4.376 inches by 9.75 inches by 1.52 inches) form factor computing module based on the NVIDIA Fermi GPU. This module comprises a computing subsystem with a GPU and high speed memory.
Different Tesla™ graphics processing unit (GPU) PCI cards
| Models | Number of cores | Core Frequency | Single precision performance | Double precision performance | Memory size (#2) | Memory Bandwidth | Remark |
| M2090 | 512 | 1331 Gflops/s | 665 Gflops/s | 6 GB GDDR5 | 177 GB/s | ||
| M2070[Q] (#1) | 448 | 1.15 GHz | 1030 Gflops/s | 515 Gflops/s | 6 GB GDDR5 | 150 GB/s | |
| M2050 | 448 | 1.15 GHz | 1030 Gflops/s | 515 Gflops/s | 3 GB GDDR5 | 148 GB/s | |
| M1060 | 240 | 1.3 GHz | 933 Gflops/s | 78 Gflops/s | 4 GB GDDR3 | 102 GB/s | Obsolete |
Note#1: Q means Quadro graphics features are also enabled.
Note#2: With ECC on, 12.5% of the GPU memory is used for ECC bits. For example, 3 GB total memory yields 2.625 GB of user available memory with ECC on.
