Now that PC gamers have the dual-GPU monstrosity that is the Radeon R9 295X2 to sink their teeth into, for AMD’s next GPU act, they’re reportedly working on something a little less powerful and a little more affordable called Tonga. Don’t be dismayed though; there is reason to be excited.

According to, AMD is working to make Tonga a more power-efficient GPU, so it likely won’t be used to power high-end graphics cards. However, this doesn’t mean that Tonga-based cards will be slouches either, and will likely compete head-to-head with Nvidia Maxwell GM107-based graphics cards.

So what’s on the list of GM107-powered cards? That would be the Nvidia GeForce GTX 750 Ti, which combines solid mid-range performance, excellent power efficiency, and an affordable price tag (in the $150 range) to boot. On top of that, the 750 Ti occupies a single slot expansion slot, requires no additional power connector, and demands only 60 watts of juice. This means that you can slot a 750 Ti into PCs with power supplies that provide as little as 300 watts to work with.

As for details regarding specs, Videocardz suggests that Tonga-based cards will sport 2GB of RAM, but no other information is available. However, they’re expected to support existing tech, including Mantle, TrueAudio, and CrossFire as well.

If geography is your strong suit, you might have recognized that by adopting the Tonga name, AMD is keeping with the island/volcano theme from a naming standpoint. It did the same with their Hawaii-branded GPUs, and Vesuvius codename for the 295X2 as well.

So when should we expect Tonga-based cards to hit the market? They may arrive by July, and should be available sometime in August at the latest. Additional details could be revealed during Computex, which will be held in Taipei early next month.

Nvidia’s RTX 4060 Ti may be more affordable, but will it be a good value?
RTX 4070 seen from the side.

Nvidia's RTX 4070 only launched a few days ago, but rumor has it that Team Green already has another GPU coming out soon -- the RTX 4060 Ti.

Reportedly scheduled for a May release, the GPU might be much cheaper than the RTX 4070, but even that price cut might not be enough to make it competitive against some of the other top graphics cards.

Nvidia GeForce RTX 4070 vs. AMD Radeon RX 6950 XT: a close call
Two RTX 4070 graphics cards sitting side by side.

Nvidia's new release, the RTX 4070, shakes things up in the GPU market. After a long spell of only releasing overpriced graphics cards, Nvidia seems to have altered its pricing strategy for the RTX 4070. While it's hard to call it cheap, it's certainly affordable, and it offers performance that makes it a good midrange option.

However, Nvidia's latest addition to the ranking of the best graphics cards has an unexpected rival in the previous generation of GPUs. AMD's RX 6950 XT is similarly priced, but can it keep up with the RTX 4070? Check out our benchmarks and find out how these two cards stack up against each other.

Nvidia may have another monster GPU in the works, and the price could be outrageous
GeForce RTX logo is shown on the side of a graphics card.

Today, yet another sign of an upcoming Nvidia Titan RTX Ada GPU appeared -- the card's specs were spotted in a shipping manifest. This suggests that engineering samples of the monstrous GPU might be on their way to various development centers around the globe.

Everything points to the Nvidia Titan card making a big comeback in this generation, and the development seems to be farther along than it initially seemed to be. There's a catch, though -- how many people will even be able to afford it?
