The RX 7900 GRE vs RTX 4070, by the numbers
The time has never been better to consider a new mid-range graphics card now that AMD made its latest GPU available worldwide. Naturally, potential buyers are going to compare the RX 7900 GRE vs RTX 4070, given their close proximity in price, but it’s also important to consider what they each offer in terms of performance, features, and overall value for your money.
The AMD Radeon RX 7900 GRE is a curious graphics card, launching in February 2024 after being launched exclusively in China back in June 2023, but it’s now available to the rest of the world and offers phenomenal performance for a far more palatable price tag than many of the best graphics cards on the market right now. With the promise of the Big Navi 31 die and 16GB VRAM under the hood, it even proves itself to be one of the best 4K graphics cards for those who are on a tighter budget but want some of that sweet, sweet 2160p gaming (with appropriate settings tweaks).
The RTX 4070 has had something of a resurgence recently, having been effectively replaced by the RTX 4070 Super back in January of this year. The latter card offered 20% more CUDA cores at the same $599 price point, essentially getting you significantly more performance without the need to splash out. But that release also dropped Nvidia’s suggested retail price of the Nvidia RTX 4070 by about 10%, making it an even stronger contender for the title of best 1440p graphics card.
But there’s more to it than all that, and while we’re fond of both mid-range GPUs, we wouldn’t be TechRadar if we didn’t dig deep into our test bench to put each of these fan-favorites to our extensive battery of performance tests to find out which one comes out on top.RX 7900 GRE vs RTX 4070: Price
When weighing up a mid-range graphics card, the pricing is always paramount. The brand new RX 7900 GRE comes in clutch with an advantage straight out of the gate with its recommended retail price of just $549 / £529.99 / AU$929. In contrast, the RTX 4070 launched at $599 / £589.99 / AU$999 for the Founders Edition model, but has also dropped down to $549 / £529.99 / AU$929 in February.
What’s particularly aggressive about the RX 7900 GRE is how it slots into the current RDNA 3 lineup, being just $50 more than the excellent AMD RX 7800 XT from last year. In comparison, the RTX 4070 is quite the jump up from its sibling, the Nvidia RTX 4060 Ti, which starts at $399 in the US.
On price alone, then, this would appear to be a tie between the RX 7900 GRE vs RTX 4070, but price isn’t the same thing as value, and in the case of the RX 7900 GRE, it’s overall performance-to-price ratio after our testing reveals that it gives you more for that investment, giving it the decisive edge here.
Winner: AMD Radeon RX 7900 GRERX 7900 GRE vs RTX 4070: Specs
AMD’s RX 7900 GRE immediately stands out as a mid-range GPU by offering 16GB GDDR6 VRAM on a 256-bit memory bus. It’s built on the AMD Navi 31 die with a total of 5,120 Stream Processors. By comparison, the RTX 4070 is built on the AD104 die with a total of 5,888 CUDA cores and 12GB GDDR6X memory on a 192-bit memory bus.
There we see the immediate architectural differences between mid-range RDNA 3 and Ada respectively. The former opts for a larger memory bus with a higher amount of slower memory, compared to the latter’s lower memory pool that’s considerably quicker. Despite their differences, the two models are remarkably close in total bandwidth available with the GRE boosting 576 GB/sec to the RTX 4070’s 504.2 GB/sec.
That slight lead in bandwidth comes at the price of increased power draw, however. That’s because the 7900 GRE has a 260W TDP compared to the 4070’s 200W TDP, for a difference of 30%.
