Which GPU to buy in 2021?

Since we have discussed all GPUs with regard to gaming as well as mining capabilities, we’ll divide this section into two parts, looking at both these factors.

Which GPU should you buy for crypto mining?

All the aforementioned GPUs contain strong mining capabilities in general. However, when they are pitted against each other, some major differences come to the fore. 

Although Nividia’s CMP 40HX is designed specifically for mining and has its strong points, it’s ultimately a low-end mining option by Nvidia, especially keeping in mind that the 50HX and upcoming 90HX blow it away in almost all aspects. 

The Nvidia RTX 3080, Radeon RX 6800 XT and RX 5700 are all strong contenders in their own right, with good hash rate levels and processing speeds. However, miners typically seek to mine for very long durations, and the possibility of the cards heating up is very real. There is a high probability that you’ll need to wait for a very long period of time to realize a good ROI with these options, if at all.

That leaves the Nvidia RTX 3090 as the last GPU standing. Its incredibly high 24GB memory, coupled with the jaw-dropping hash rate of over 120 MH/s, make it an ideal option for miners, even for the longest durations. Yes, it is priced significantly higher than the other GPUs discussed in the article, but the main thing to keep in mind here is that if your priority is crypto mining, there genuinely is no better option than the RTX 3090. 

It’s understandable if you want to forego the powerhouse for less costly options in terms of gaming, but when it comes to mining, you should cough up more cash and get your hands on the RTX 3090. You’ll have the best possible shot at recouping your investment a few months down the line, so go for it!

Nvidia also hinted on limiting graphic cards capability for mining to keep the availability of its top hardware for gaming users. 

Which GPU should you buy for gaming?

The CMP 40HX is made primarily for mining, so we’ll not consider it here. Moreover, although the RX 5700 XT has good enough gaming specs, its primary strength also lies in the mining department. All the other three among Nvidia’s GeForce RTX 3080, GeForce RTX 3090 and AMD Radeon RX 6800 XT pack a real punch in terms of overall gaming performance, but when it comes to choosing which one to go for, various factors come into consideration. 

The Nvidia GeForce RTX 3090 graphic card is the clear winner when it comes to gaming, but there is a caveat – at $1500, it’s priced way higher than the other two. If you are a deep-pocketed enthusiast who doesn’t mind spending exuberantly for the absolute best performance possible – both gaming and general – then it’s the GPU to go for. But if price is your concern, you should narrow the options down to the other two.

Even though Nvidia GeForce RTX 3080 is priced $50 higher than AMD Radeon RX 6800 XT, its Ampere architecture brings more to the table in terms of performance improvements than the latter’s RDNA 2 architecture. Furthermore, RTX 3080’s DLSS technology significantly improves the image resolution of games with minimal impact on the FPS rate. As such, RX 6800 XT doesn’t offer a direct counterpart to DLSS.

From the 10-game DirectX Ray Tracing benchmark comparison at 1440p resolution above, we can see that RTX 3080 holds an edge over RX 6800 XT in all but two games – Godfall and Dirt 5. The overall average of 61.5 FPS across the 10 games is better than RX 6800Xt’s 45.8.

For all these reasons, you should shell out a little more cash and go with Nvidia’s GeForce RTX 3080 – the extra $50 shouldn’t be a reason to give up its impressive features and slightly better overall gaming performance.
