Tesla K8: specs and benchmarks
Aggregate performance score
Tesla K8 provides poor gaming and benchmark performance at 9.65% of a leader's which is GeForce RTX 4090.
Summary
NVIDIA started Tesla K8 sales 16 September 2014. This is a Kepler architecture desktop card based on 28 nm manufacturing process and primarily aimed at designers. 8 GB of GDDR5 memory clocked at 1.25 GHz are supplied, and together with 256 Bit memory interface this creates a bandwidth of 160.0 GB/s.
Compatibility-wise, this is a single-slot graphics card attached via PCIe 2.0 x16 interface. Its manufacturer default version has a length of 241 mm. 1x 6-pin power connector is required, and power consumption is at 100 Watt.

Octane Render OctaneBench
This is a special benchmark measuring graphics card performance in OctaneRender, which is a realistic GPU rendering engine by OTOY Inc., available either as a standalone program, or as a plugin for 3DS Max, Cinema 4D and many other apps. It renders four different static scenes, then compares render times with a reference GPU which is currently GeForce GTX 980. This benchmark has nothing to do with gaming and is aimed at professional 3D graphics artists.
