XFX R7790 Black Edition OC 2 GB Review
Value & Conclusion »Temperatures
Temperatures are great, which is of no surprise with such a power efficient graphics processor. I only wish XFX had reduced the fan noise a bit by allowing slightly higher load temperatures. There's certainly enough temperature headroom for that.
| GPU Temperature Comparison | ||
|---|---|---|
| Idle | Load | |
| XFX HD 7790 Black Ed. | 30°C | 64°C |
| PowerColor HD 7790 Turbo Duo | 32°C | 68°C |
| Sapphire HD 7790 Dual-X | 30°C | 59°C |
| ASUS HD 7790 DC II OC | 26°C | 59°C |
cooler design, and production variances. This table just serves to provide
a list of typical temperatures for similar cards determined during TPU review.
Clock Profiles
Modern graphics cards have several clock profiles that are selected to balance power draw and performance requirements.The following table lists the clock settings for important performance scenarios and the GPU voltage that we measured. We performed the measurement on the pins of a coil or a capacitor near the GPU voltage regulator.
| Core Clock | Memory Clock | GPU Voltage (measured) | |
|---|---|---|---|
| Desktop | 300 MHz | 150 MHz | 0.81 V |
| Multi-Monitor | 300 MHz | 1600 MHz | 1.01 V |
| Blu-ray Playback | 1073 MHz | 1600 MHz | 1.20 V |
| 3D Load | 1075 MHz | 1600 MHz | 1.19 V |
| CCC Overdrive Limits | |
|---|---|
| Core | 1200 MHz |
| Memory | 1600 MHz |
