AMD's Radeon HD 7790 features the "Bonaire" silicon featuring 2.08 billion transistors compared to 1.5 billion on Cape Verde. The Bonaire core feature 896 stream processors  56 TMUs, 16 ROPs, 2 Prim/Clock, Dual Tessellation units and a 128-bit GDDR5 memory interface. The reference model of the card ships with 1 GB of VRAM so its up to AIBs to offer higher VRAM versions. Core clock is maintained at 1 GHz while memory operates at 6 GHz speed at effective rate churning out 96 GB/s bandwidth.

  • 1000MHz Engine Clock
  • 1GB GDDR5 Memory
  • 1500MHz Memory Clock (6.0 Gbps GDDR5)
  • 96GB/s memory bandwidth (maximum)
  • 1.79 TFLOPS Single Precision compute power
  • GCN Architecture
  • 14 Compute Units (896 Stream Processors)
  • 56 Texture Units
  • 64 Z/Stencil ROP Units
  • 16 Color ROP Units
  • Dual Geometry Engines
  • 128-bit GDDR5 memory interface

Based on the award-winning GCN Architecture, AMD Radeon™ HD 7700 Series GPUs are built to game with the world’s most advanced 28nm GPU design. And the AMD Radeon™ HD 7790 GPU is packed with incredible features, like automatic overclocking with AMD PowerTune technology, or ultra-resolution gaming with AMD Eyefinity technology. And that’s just the beginning, because these are the world’s most advanced graphics. For everyone. AMD

The GPU while configured to operate at 1 GHz core clock can dynamically adjust its core frequency with the new AMD clock adjustment technology which operates the same way as NVIDIA's boost making the GPU perform much more efficiently. Card is supplied power through a single 6 Pin connector and comes with an rated TDP of 85W, the AMD Radeon HD 7790 would retail at $149 with custom parts adding in the cost.
