3DMark
3DMark is the latest version of this hugely-popular synthetic benchmark. Making use of DX11 features such as tessellation, compute shaders and multi-threading, it provides modern-day results and is available as a free download.
Palit's core clock speed is lower than the MSI, so it's the frame-buffer speed advantage that allows the Super JetStream to nip ahead of the Gaming 4G. The synthetic results are good and suggest that Palit's card will be able to compete with others that are clocked in higher on core.
