Radeon HD 7790 "Bonaire" in SweClockers test lab
Shortly AMD releases a new graphics card in the Radeon HD 7700 series, but not with the graphics processor Cape Verde.
Without a new generation of graphics cards in sight works both AMD and Nvidia to complement the existing series. The closest are two models in the lower middle class: Radeon HD 7790 and a remastered version of the GeForce GTX 650 Ti.

AMD is first, and has already started sending out test samples to manufacturers and the media. Radeon HD 7790 is based on the graphics processor "Bonaire", which first and foremost is for laptops, but now are used in separate graphics card.
A GPU-Z screenshot taken for the card reveals clock speeds of 1075 MHz core, and 1600 MHz memory, which results in a memory bandwidth of 102.4 GB/s. A point to note here is GPU-Z 0.6.8 doesn't officially support HD 7790 "Bonaire," and so some of the values which are not reported by the driver, such as stream processor count, TMU/ROP counts, and even memory bus width could be unreliably reported. Values such as clock speeds and memory size are driver-reported, and could be accurate.
In Fire Strike, the card scored 4026 points (graphics) compared to the 4395 points of Radeon HD 7850, which is just 8.3 percent slower. It's a similar story with 3DMark 11, where the HD 7790 scored 1583 points (graphics) compared to the 1734 points of HD 7850, just 8.7 percent slower. The reviewer is using a beta Catalyst driver bearing version number 12.101.2.0.
The actual circuit board measures 21.5 inches and is equipped with a 6-pin PCI Express connector, which provides a maximum power of 150 W. In other visible connections for two DVI, one HDMI, and DisplayPort, and support for all common features, including AMD HD3D and Eyefinity. It can pair with another of its kind, only.
Radeon HD 7790 is expected to show up sometime in the next few weeks, probably by the end of March or beginning of april.
This model is for price point around 1200 Euros including VAT.

nVidia 655Ti rushed out to battle 7790
March 15th, 2013 at 8:12 am - AuthorJulesIn life, people walk in a lot of different directions. It’s often said that a leader without followers is just a bloke taking a walk. You know you’re leading when you look over your shoulder and find that the next person is right behind you – taking the same steps/turns you’re taking. KitGuru enters the world of the Radeon 7790 (Bonaire) and GTX 655Ti.
Running a successful retail business means carrying just the right amount of stock at all times.
Understocked and you have nothing to sell customers – but at least you have cash and can buy new products for your store.
Overstocked and your shelves are full of product that no one wants – and you have no cash to buy alternatives.
OK, so that’s retail 101 taken care of.
The worst situation you can face is being overstocked when a new product launches – with a better specification at a lower price. This is something that AMD partners experienced just before Xmas 2012 when products like the VTX3D 7870 Black (Tahiti LE) launched more than £70 cheaper than the 7950 – but with similar performance.
Now, it seems, it’s nVidia’s go. And this overstock will happen close to the significant £100 mark.
Why £100?
Well the vast majority of graphic cards sold in the world exist just under this price point. It actually might be slightly higher than £100 – but not by much. Push the price to £150 or £200 and the sales figures drop rapidly.
Around 26th March 2013, nVidia retail partners will be able to get their paws on a GeForce GTX 655Ti for $179 (approx £120). This has been designed to go head-2-head with AMD’s upcoming Radeon HD 7790. Having seen advanced specs on teh new Radeon, nVidia has been forced to move and move quickly.
Sounds good, so what’s the problem?
Well for customers (i.e. you, dear reader), the problems are minimal. But for the channel, it will be fun. Here’s a specification – we’ll explain the ‘twist’:-
- nVidia 6 Series GPU
- 2GB GDDR5
- 192-bit Memory Interface
- 6GHz Memory Clock
- Core Clock around 980MHz
- 4 Head Output
If that sounds familiar, it’s because that is the current offer from MSI and others on the GTX 660 – which sells around the £170 mark.
It’s actually the proposed specification for the new GTX 655 Ti – which could be closer to £120.
Expected performance on the new card is rumoured to be around 3,000 in 3D Mark Fire Strike. Almost exactly the same as the Radeon HD 7790 is expected to score.
We’re expecting the Radeon HD 7790 to be £10-20 cheaper than the new GTX655 Ti.
