Sapphire Radeon HD 7790 

Released March, 2013
  • 1 GHz
  • 1 GB GDDR5
7 Out of 10

Overclocking potential is good, but GPU clock cannot match the clocks of Sapphire's card, which is the best overclocking HD 7790 we reviewed so far.

Overclocking is decent, especially considering that the card is already overclocked out of the box.

Reviews Word on the street for the Radeon HD 7790


9.3
The card features a custom-design dual-fan cooler and offers factory-overclocked speeds of 1075 MHz core and 6.40 GHz memory for a premium of just $10 over AMD's suggested reference design retail price of $149.

What People Are Saying Give it to me straight

Performance

It is well known for its good cooling performance and low noise levels.
by techPowerUp! (Mar, 2013)
When scaling works, it works very well, improving performance by around 80% compared to a single card.
by techPowerUp! (Mar, 2013)
The most interesting feature of sub-$200 graphics cards is their ability to transform from mid-range single-card solutions into high-end dual-card ones through the use of multi-GPU technologies like AMD CrossFire and NVIDIA SLI.
by techPowerUp! (Mar, 2013)

Overclocking

Overclocking on our card worked amazingly well, reaching 1265 MHz GPU.
by techPowerUp! (Mar, 2013)
GPU overclocking worked extremely well—better than the ASUS card we also reviewed today.
by techPowerUp! (Mar, 2013)
Pricing of the reference design HD 7790 is very reasonable with $149, and ASUS is asking a fair $10 price premium for their overclocked version with the better cooler.
by techPowerUp! (Mar, 2013)

Gaming

Especially gaming power draw is impressive.
by techPowerUp! (Mar, 2013)
The card will be inaudible in any modern system regardless of what you do—even during demanding gaming.
by techPowerUp! (Mar, 2013)
This makes the HD 7790 capable of full-HD 1080p gaming, but in some titles, you might have to go easy on anti-aliasing levels, or reduce details slightly for the best gaming experience.

The ASUS HD 7790 DC II that we also reviewed today is a bit quieter in gaming, but not by much.
by techPowerUp! (Mar, 2013)
The game uses a heavily modified version of Epic's Unreal Engine 3 that is still running in DirectX 9 mode, but it does offer plenty of appealing visual effects.
by techPowerUp! (Mar, 2013)

Power

Temperatures are great, which is of no surprise with such a power efficient graphics processor.
by techPowerUp! (Mar, 2013)
Please note how Sapphire rotated the power connector so that it's now sitting on the long "top" edge of the card, like on NVIDIA cards.
by techPowerUp! (Mar, 2013)
Especially gaming power draw is impressive, making it the most power efficient GPU ever.

Mantle will help this greatly and it's currently retailing for around $134 at amazon with a discount http://amzn.to/VPcxcj. Perfect for low budgeters...
No, it shouldn't.
Will it bottleneck core 2 duo e7300
