But a new rumor suggests that AMD’s flagship Big Navi card will only be able to compete against Nvidia’s second tier card, the RTX 3080, rather than the top enthusiast card, the RTX 3080 Ti. and to date have been pretty accurate for both NV's and AMD's cards. But unless AMD’s claims are false or my calculations were wrong, this should be close to the actual performance theoretically.But RDNA 2’s performance/watt has even surpassed Zen 2. It would be a decent leap in performance over the 1st gen rdna chips. “According to the same sources AMD is aiming to launch the ‘Big Navi’ as a direct competitor to the soon to be launched RTX 3080, and not as a competitor to NVidia’s highest performing part as has been widely reported (let alone beat it).
While AMD has historically struggled to beat NVIDIA’s best offerings, a new leak might turn the tables. But a recent leak has Big Navi tipped at being 40 to 50 percent faster than a GeForce RTX 2080 Ti, Nvidia’s top-of-the-line graphics card. AMD has already invested a lot in the console marketplace and to see them enter the PC enthusiast-centric market would be a welcome move.At CES 2020, AMD CEO Lisa Su also teased the arrival of Big Navi this year. In short, an RDNA 1 based 80 CU card is out of the question. Remember, earlier we arrived at a perf/watt figure of 81.4 for Big Navi while assuming 50% perf/watt improvement vs 5700 XT (AMD’s claims).Yes, there’s another 50% bump in performance/watt. Unlike Zen 4 based EPYC Genoa, they decided not to reveal the fabrication node of RDNA 3. Anthony Garreffa | Jan 22, 2020 at 8:08 pm CST Image: AMD. AMD Big Navi GPU: RTX 2080 Ti killer, but will lose to RTX 3080 AMD's new RDNA2-powered Big Navi GPU might keep up with NVIDIA's new GeForce RTX 3080. We should expect 512-bit GDDR6 on Big Navi and if there’s still a bottleneck, AMD will use HBM2e.That means Big Navi will be around 144.2% faster than Vega 64.With RDNA 1, it was possible for AMD to launch an RTX 2080 Ti competitor that consumes more power. Gotcha. Ampere is coming out this year which will reportedly cut down on that end a lot compared to Turing. The rest 75% came from Architectural improvements.If the RX 5700 XT was on N7+ (15 to 20% density improvement), its die size would be around 213 to 220 mm². Related: Nvidia Ampere. Either way, PC gamers will end up winning.There was a problem. RDNA 2 could be AMD’s Zen 2 moment for Graphics Cards.RDNA 2 based GPUs will also support Hardware Accelerated Ray Tracing & Variable Rate Shading.With 7nm+ for RDNA 2, we are expecting 15% lower power at the same clock speeds. Sources: AMD’s “Big Navi” Only 15 Percent Better Than RTX 2080 Ti by Tsing Mui July 30, 2020 July 30, 2020. AMD has officially announced that they are working on two separate GPU architectures, RDNA & CDNA.If Big Navi was on RDNA 1 with 80 CU, it would be around 35-40% faster than RTX 2080 Ti while consuming around 420 Watts and that’s not feasible and would require a significant reduction in clock speeds. For better Ray Tracing Performance, Big Navi will require more bandwidth and a lot more cache. You also have to keep in mind their approach to the architectural process which is different from the Green team.That will have 500w power consumption i guess Yes, other variables would also limit the performance to some extent. The specification of Big Navi is based on rumors and some calculations.With these numbers, AMD wouldn’t even require 80 Compute Units to defeat RTX 2080 Ti.Here’s what AMD expects from RDNA 2.But after turning Ray Tracing On, I expect Nvidia’s Ampere Flagship to deliver higher FPS than Big Navi. please like and subscribe and hopefully i will see you next time. If rdna2 matches the 2080 ti, it would be acceptable if it only costs around 400-500 usd. The second statement ‘Top-of-Stack GPUs with Uncompromising 4K Gaming’ gives a clear hint that there will be a flagship chip this time around.Yes, you heard that right.
But, if it ends up being around 700-800 usd, itll be instantly doa.
