Is nvidia better than amd: Does It Really Matter Which GPU You Buy?

Does It Really Matter Which GPU You Buy?

When it comes to graphics cards, you’ve got two options: AMD or Nvidia. These two tech behemoths have dominated the graphics card conversation for nearly two decades, and it’s been a long time since any other tech outfit took a good shot at the two.

Intel’s upcoming Arc Alchemist graphics card aside, choosing between the two is difficult. If you buy a new GPU, you’re either buying from Team Red or Team Green. So, does it really make a difference who you buy from? Isn’t all GPU performance roughly similar? Can’t you expect a similar level of gaming performance, no matter if you buy an Nvidia or an AMD GPU?

AMD vs. Nvidia: Does It Really Matter?

PC hardware enthusiasts worldwide are spitting coffee across their screens as they read. Debates about the merits of each GPU manufacturer are a never-ending source of conversation, especially since AMD rolled its socks up and clawed back Nvidia’s considerable advantage with the launch of its Ryzen GPUs.

Then there are advanced memory caches, differences in superscaling implementation, development of Compute Units and CUDA Cores, and on and on it goes.

However, for many would-be gamers, those (admittedly very interesting) specs don’t actually mean much. The raw figures and processing power on paper don’t marry to real-world performance, and not everyone has the time (or want) to learn about the differences between AMD’s Compute Units and Nvidia’s CUDA Cores.

For most users, the simple question is, will this graphics card make my games look better? Will installing an AMD GPU give me better frame rates than an Nvidia GPU? And even then, that’s assuming you’re using gaming hardware that allows you to swap your hardware out and make that decision. If your primary gaming machine is a console like the PlayStation 5 or Xbox Series X, the conversation will wash over you, as both machines use AMD hardware. There, you’re an AMD fan, and you didn’t even know it—welcome to Team Red.

AMD vs. Nvidia: Who Makes the Best GPUs?

Perhaps the question is best broached from another perspective. Who makes the best graphics cards out of Nvidia and AMD?

Again, answering the question isn’t easy without getting involved with specs and costs. But if you’re building out or buying a new PC, these are valid questions, and understanding at least some of what’s being sold to you is important. At the very least, you’ll understand more about what to expect from your graphics card, and you could save yourself some extra pennies when PC hardware prices continue to rise.

So, let’s look at a few factors that might help you figure out which graphics card you want to buy.

1. Performance

At the top end of the GPU market, you’ll find incredible hardware like the Nvidia RTX 3090 and the AMD RX 6900 XT, and the RTX 3080 and RX 6800 XT. The Nvidia RTX 3070 and RTX 3060 Ti bookend AMD’s RX 6700 XT, but they’re all there in the mix.

All of these equivalent cards offer similar performance, give or take a few frames per second, along with the other hardware in your machine. However, Nvidia typically edges just ahead in terms of outright power, boosted by the additional tech it brings to the table, such as DLSS, which is undoubtedly better than AMD’s Fidelity FX.

So, in terms of gaming performance, an Nvidia GPU is likely the better option, but you won’t go wrong with an AMD card either.

2. Price

Next up, price. If performance is similar outside of advanced features like ray tracing and upscaling, the next best metric is price. Even if you think it doesn’t matter which GPU manufacturer you choose, the difference in price between AMD and Nvidia may cause you to reconsider.

Price is one aspect where AMD typically beats out Nvidia. For example, Nvidia’s RTX 3080 has an MSRP of $699, while the equivalent AMD card, the RX 6800 XT, has an MSRP of $649.

Now, what’re 50 bucks when you’re already spending that much on a GPU? The difficulty is that currently, GPU prices are drastically inflated due to chip shortages, manufacturing issues, energy inflation, crypto mining, scalpers, and so on. Where there was just a $50 gap between these two equivalent GPUs at launch, the current price is much, much higher—and with a larger gap between the two.

According to Tom’s Hardware, the average price for an Nvidia GeForce RTX 3080 on eBay was $1,783 in December 2021, while the AMD Radeon RX 6800 XT was substantially cheaper, averaging $1,387. That difference of around $400 is significant, maybe allowing you to spend extra on other hardware components such as more or faster RAM.

3. Availability

Following on from that, availability is another problem facing both GPU manufacturers. As Nvidia’s GPUs are better for cryptocurrency mining and hold a slight edge when it comes to gaming performance, they’re harder to get hold of (due to global shortages, as above). As a result, you’ll struggle to find an Nvidia at MSRP. Whereas, you stand a better chance of picking up an AMD GPU at a lower price, with wider availability in general.

So, does it matter which GPU you buy? When it comes to availability, it may come down simply to what is available when you have the funds to spend and not much else.

Which GPU Should You Buy? AMD or Nvidia?

When it comes down to it, the current state of the GPU market doesn’t make it easy for anyone to buy new hardware, let alone be picky when it comes to choosing between Nvidia and AMD. If you can hold out or splash the extra cash required for the GPU you really want, go for it. Otherwise, don’t get too hung up on the smaller details.

Remember, if you’re upgrading from an older GPU, say an Nvidia GTX 980 or an AMD RX 580, to a sparkling RTX 3080 or RX 6800 XT, your graphics experience is going to improve an unfathomable amount, regardless of extra features, cache size, upscaling, or otherwise. Sure, Nvidia’s ray tracing tech is streets ahead of AMD’s equivalent. But a top-end AMD GPU will still play your games at the highest settings at 4K, which is more than enough for most people.

AMD vs Nvidia, Which is Better? (Updated 2023)

The never-ending war between Team Green and Team Red.

How many times have you heard people fighting over which graphics card maker is the best? There has always been Team Green or Team Red, so in the never-ending battle of the GPU, who wins? AMD or Nvidia?

One thing is true – never ask a group of gamers whether NVidia is better than AMD or the other way around because you’ll probably start a fight. All jokes aside, let’s see which video card maker is the best in 2020.

In 2021, AMD is better than NVidia because of superior price per performance. The technical capabilities are similar, but AMD is simply more affordable.

AMD vs Nvidia – Price Per Performance

The debate can always be settled when you look at price per performance. And since both Nvidia and AMD have released the latest GPU’s, let’s take a look at some numbers.

AMD has released Radeon RX 6000 series GPUs and will soon be available for purchase online or in stores. There are two versions of RX 6800 and an RX 6900. The three RX 6000 series GPUs come with the same RAM, Infinity Cache and the option Rage Mode, but have different clock speeds and compute units.

The most powerful video card from AMD is the RX 6900 XT, which starts at $999. Then, the second best AMD GPU is the RX 6800 XT ($679), which has more compute unites than the RX 6800 ($579).

Meanwhile, Nvidia has launched the RTX 30-series – RTX 3090 ($1,500), which is the flagship, RTX 3080 ($700), the mid-tier GPU and the low-range RTX 3070 ($500), which should replace the insanely expensive RTX 2080 Ti.

Most consumers would choose the mid-tier RX 6800 XT since it’s more accessible in terms of its price. Sure, the RX 6800 is $100 cheaper, but here’s why it may not be the greatest choice.

Both the RX 6800 and the RTX 3070 offer great performance at 4k and 1440p. But what should we choose?

AMD’s RX 6800 is $579, while Nvidia’s cheapest GPU – the RTX 3070, which directly competes with AMD’s, starts at $500. The two GPU’s are nearly the same in terms of performance, so the $79 extra makes the RX 6800 a loser in terms of price per performance.

The $679 RX 6800 XT however, should lead the fight since it directly competes with the RTX 3080, which is $700. So, there’s a $20 difference – a thing that shouldn’t be an issue since both GPUs offer great performance.

AMD wins in the flagship battle since its top tie GPU is $500 cheaper than Nvidia’s RTX 3090.

AMD vs Nvidia – GPU Architecture

Now, when it comes to calculations, both AMD and Nvidia GPUs have the same ones but differ in the implementations.

Nvidia shines at secondary calculations, where PhysX and most GameWorks libraries can only be used with Nvidia video cards.

The latest AMD architecture is RDNA 2, which powers the recently released RX 5000 series. Meanwhile, Nvidia’s latest architecture is Ampere, which is found in the latest GeForce 30 series that was released this fall.

 

The AMD and NVidia History

Here’s a short look at the two companies’ history.

AMD (Advanced Micro Devices) was founded in 1969 and started making microchips. Over the years, the company had acquired some businesses, including ATI Technologies in 2006, which became their GPU division. Both producing CPUs (Ryzen) and GPUs (Radeon), AMD is definitely a household name.

Nvidia is a younger company, as it was formed in 1993. Since it was founded, it began producing graphics cards, with the Riva TNT being the first major product (released in 1998). The GeForce brand has been around for nearly two decades. Nvidia has been producing 17 generations of GPUs so far.

Even though both AMD and Nvidia have been producing chips for different devices, even mobiles, most of the discussions revolved around their graphics products.

AMD vs Nvidia- Final Thoughts

There’s one aspect we should all take into consideration before deciding which GPU to choose: availability. If you’re not necessarily a Team Red or Team Green geek, the best GPU on the market right now is the GPU that is actually… on the market!

For an in-depth look on how AMD fares against Nvidia, we have three reviews of each Radeon RX 6000 series GPU compared to each Nvidia 30-series GPU. Check this Radeon RX 6800 review here, the Radeon RX 6800 XT review here and click this link to read the Radeon RX 6900 XT review. You’ll be able to see benchmark tests and more details about the last gen GPUs.

We looked through the benchmarks provided by AMD and we have to admit that Nvidia should be a bit worried. As we mentioned in our reviews liked above, with both Rage Mode and Smart Access Memory, the RX 6000-series surpasses the GeForce 30-series GPUs by at least 5 FPS and up to 30 FPS. But this is only thanks to a system that contains a Ryzen CPU and a 500-series chipset. So if you’re looking to build a similar setup, the RX 6000-series is a great choice.

So we see AMD rising to challenge Nvidia with the latest RX 6000-series. However, we will have to see more tests before placing the crown on AMD’s head.

What we do know is that AMD and Nvidia will never stop competing against one another. But this is something we should be happy about, because competition is what leads to innovation. And, let’s not forget that competition will also mean getting the best performance for the right price.
