AMD’s “Big Navi” graphics card may be more powerful than we expected.
In a recent Tweet from a prolific leaker who allegedly works at TSMC (where AMD chips are being made), we saw a claim about AMD’s Navi 21. Now, even though Wccftech stated that the leaker has been reliable in the past, we must take this rumor with a grain of salt.
It seems that the Big Navi (rumored to be named Radeon RX 5950XT) will have a die size of 505 mm², meaning the GPU will be quite chunky.
Looking at the RX 5700 XT, which has a 251mm² die and 40 CUs (compute units), we could be expecting to see the Big Navi feature double the CUs. With 80 CUs, the Big Navi will have 5,120 stream processors.
Add the next-gen architecture – RDNA 2, and the Big Navi will certainly be big in terms of size and performance.
Is double-the-size equal to double-the-power?
Looking back at previous GPUs, we see there are plenty of other features we must take into consideration when it comes to performance.
If AMD uses the extra CUs for ray tracing, the CU count goes down. AMD must find the right balance between clock speeds, cooling, and power consumption.
AMD did mention that RDNA2 will see a 50% boost in performance per Watt compared with the previous architecture.
AMD’s 2020 GPUs have passed RRA certification, meaning the company is getting ready for launch. So far, we’ve seen codenames for at least four graphics cards in an EEC filing (Radeon RX 5950XT, Radeon RX 5950, Radeon RX 5900 and Radeon RX 5800) and benchmarking results (for the flagship – Radeon RX 5950XT), meaning we can expect these GPUs to be launched in September.
Will the Big Navi be able to compete with Nvidia’s next-gen RTX 3000 series?
We will just have to see if AMD can make their Navi 21 GPU competitive for the right price, of course.
