Features Key features of the Radeon HD 7730  vs 6770 

memory bandwidth Rate at which data can be read from or stored in onboard memory

Radeon HD 7730
72 GB/s
Radeon HD 6770
76.8 GB/s
Before you try too hard to compare the number of shaders, texture units, ROPs, and memory bandwidth to AMD's Radeon HD 6670, remember that both GPUs leverage different architectures.

pixel rate Number of pixels a graphics card can render to the screen every second

Radeon HD 7730
6.4 GPixel/s
Radeon HD 6770
13.6 GPixel/s
The card being a low-end model has a short PCB design and features nothing fancy other than the propeller blade cooling solution from MSI.

texture rate Speed at which a graphics card can perform texture mapping

Radeon HD 7730
19.2 GTexel/s
Radeon HD 6770
34 GTexel/s
The main number we're on the hung for is 60 when it comes to looking at our average FPS.

floating point performance How fast the gpu can crunch numbers

Radeon HD 7730
614.4 GFLOPS
Radeon HD 6770
1,360 GFLOPS

shading units Subcomponents of the gpu, these run in parallel to enable fast pixel shading

So, while the 7730 comes up short against the 6670's shader count, we aren't expecting it to be slower.

texture mapping units Built into each gpu, these resize and rotate bitmaps for texturing scenes

The graphic card features 384 stream processors with 16 ROPs and 24 TMUs and is essentially a cut down variant of the Cape Verde GPU hence called “Cape Verde LE.
