Nvidia RTX A4000 review: GPU for benefits, tested for gaming

Shopping Shortcuts:

Today we take a look at the Nvidia RTX A4000. This is the full name of the product and it may not be what some of you think. This isn't one of the rumored new GeForce RTX 4000 series, but an amp-based GPU designed for workstation PCs. Do you focus on gaming hardware? We recently had questions about this graphics card: "Would you like to buy an RTX A4000 for gaming with an RTX 3070, and if so, how much more would you spend on the A4000?" Nvidia RTX A4000 review: GPU for benefits, tested for games

Interestingly, you can actually buy an RTX A4000 at a retailer. At the time of writing, you can buy the RTX 3070 at Newegg and several other sites for around $1,000, while the RTX 3070 Ti starts at $1,200. Meanwhile, the RTX A4000 can be purchased for around $1,300, or about 30% more than the vanilla RTX 3070. Earlier this year, Nvidia dropped the "Quadro" name for its workstation products and simply replaced the RTX A2000 with the A4000. A5000 and A6000, they were used in different amp-based applications.

First, the cores. Where the 1575MHz RTX 3070 Ti cores operate at 1770MHz, the 735MHz A4000 cores operate at just 1560MHz.

This means that under load the RTX 3070 Ti should be at least 13% higher than the A4000. There is not much difference, but there is another specification that can have a more serious impact on performance, and that is GDDR memory.

It drops to 448 Gbps. Nvidia RTX A4000 review: GPU for features, tested for games

The RTX A4000 has one advantage, which is the memory capacity. It has 16 GB of ECC memory versus 8 GB for the RTX 3070 Ti. We think that's why so many of you are interested in the A4000.

In theory, you should be able to overclock the A4000 to get the performance of the RTX 3070, but it all depends on you. It can strain cores and memory, which is of course what we want to find out.

With this in mind, it should be noted that this review focuses exclusively on the game. performance. We don't care about the benefits of the A4000 for video editing, 3D rendering, or CAD work. This may be something we look at in a separate section, but for this we need to look at a lot of game information, and of course, the whole purpose of buying the A4000 this year was to answer: is it worth buying with RTX? he got it? 3070 to play? Nvidia RTX A4000 review: GPU for features, tested for games

Since the RTX 3060 has a TDP of 170 watts, it would be surprising if the A4000 came out of the box anywhere close to the RTX 3070. However, given the small cooling of the small groove cooling fan, it is unlikely to be Too quiet, and worst of all, overclocking for maximum performance can be a problem. I hope I can get a water block for the A4000 in the future, but for now we have to rely on a reference air conditioner. Nvidia RTX A4000 review: GPU for features, tested for games

Keep the RTX A4000 on while the blower fan is on and spinning at 1425MHz at 2800rpm, which was loud, but not crazy, and is really much better than I expected at 47dB. Overclocked to 1570MHz while gaming and there was only a 10% increase in frequency. However, GDDR6 memory was overclocked from 14 Gbps to 16 Gbps, which is a huge 14% increase. This overclock was 100% stable and survived the game multiple times in 48 hours. Unfortunately, despite the A4000's overclocking, the RTX 3070 Ti has 18% more storage space for core and memory, which means it would be very difficult to match the A4000 even with an RTX 3070, let alone the Ti model. At this point, we probably just need to use the Ryzen 9 5950X test system. Let's get into this. The applied overclocking was only 7 times faster and allowed to match the 6700 XT. Unfortunately, this means that slow 12 was slower than the RTX 3070 and slow 15 was slower than the 3070 Ti, not by a huge margin, although with GeForce models we are approaching a completely different performance level.

the margins are similar in 4K, and while the A4000 does a great job in terms of high performance here, it's also significantly slower than the RTX 3060 T. The overclocked frame rate increased by 12% this time around, but it still only matched the 6700 XT, meaning it was significantly lower than the 3070 and 3070 Ti.

Going to Cyberpunk 2077 and here I have to say the A4000 is even more disappointing, only the RTX 2070 Super with an average frame box of 1440p fits 52 fps. Overclocking was fine for the other 10 additions, averaging 57 fps, but that meant the RTX 3070 was still 12 times faster, while the 3070 Ti was about 18 or 30 faster than the stock, and the A4000 was.

The A4000 was more competitive in 4K and matched the 6700 XT when it was released. The Overclocked could be compatible with the RTX 3060 Ti, although we're only talking here at 28fps, which is unplayable and certainly not acceptable given the price.

Like most modern graphics cards, the A4000 in Death Stranding bubbles at 1440p resolution with maximum in-game quality settings, averaging 123 fps or more. The overclocking feature provides 133 frames per second. That means stock, it matches the RTX 3060 Ti, and it wasn't much slower than the RTX 3070, so that's a good result.

4K lost a bit and is now 16% slower than the RTX 3070 without any overclocking and 22% slower than the 3070 Ti. So while you can deliver playable performance in Death Stranding in 4K, it's much slower than its GeForce counterpart.

The results for Horizon Zero Dawn 1440p look a bit more positive, but mostly because faster GeForce GPUs seem artificially limited and the 3060 Ti is very close to the 3070, which puts the A4000 close Very much from the RTX 3070, especially when overclocked.

Margins were very similar in 4K, the stock A4000 was slightly slower than the RTX 3060 Ti and overclocking was slightly slower than the RTX 3070, which means the 3070 Ti 14% faster than overclocking The A4000 is operating so not by a large margin, but less than ideal given that the A4000 is more expensive and should already be overclocked.

Rainbow Six Siege margin for A4000 despite unpleasant performance. Overall very intense with 222fps out of the box. However, with our maximum overclocking, it can only match the RTX 3060 Ti, so the stock RTX 3070 is 18% faster and the 3070 Ti is 25% faster.

4K results were more similar compared to stock settings, the RTX 3070 was 30% faster than the A4000 while the 3070 Ti was about 40% faster and the A4000 was only 12% faster at overclocking Our operating.

The last game we'll be covering is Watch Dogs Legion, and here we see more of the same game, although the overclocked A4000 performs much better than the RTX 3070 and is only 4% behind it at 1440p.

That's a similar story at 4K, so I'd say overclocking is one of the best results for the A4000 despite the fact that its storage is still RTX 3060 Ti compatible. Power Consumption

Where the A4000 really shines is d power consumption and that's what allows Nvidia to steer clear of the small, single-slot cooler. The total power consumption of the A4000 was 312 watts or only 320 watts when overclocked. Overclocking has indeed improved performance, but of course, there is no guarantee that all models will reach the same frequency using the A4000 voltage.

In this case, the A4000 only feeds 770 mV under load while the RTX 3070 Ti feeds 1040 mV, so there is a huge difference in voltage. This enables the 3070 Ti to operate at much higher frequencies, but also eliminates power consumption, such as using GDDR6X memory. Unfortunately, Nvidia doesn't allow you to work at A4000 voltage, or at least I don't yet understand how it works. It uses slightly less power than the Radeon RX 6600 XT in Doom at 1440p, while offering 20 better performance. Or, compared to the RTX 3060, we see a 13% reduction in total system usage for the same level of performance.

Performance Summary

In this step, we reviewed 6 benchmarks out of 12. The games we tested, but at this point we think you have a good idea of ​​where the RTX A4000 is, so let's look at the average data of 12 games .

Let's start with the 1440p results. On average, the A4000 is a bit slower than the RTX 3060 Ti, so it's not great considering the price. The best I can get at a constant voltage is an 11% performance boost, which allowed the A4000 to beat the RTX 3060 Ti, but stock the 3060 Ti. This means that at best, the RTX 3070 will be 6% faster and the 3070 Ti 14% faster.

The A4000 isn't bad considering its high performance, and the Radeon 6700 XT obviously performs very well, but it still comes at a price. But given the price and availability of all parts at the moment, I can see how reasonable the A4000 is for some of you.

The margins are faster than the RTX 3070 and the 3070 Ti are about the same at 4K, so the larger A4000 memory hasn't been used here yet, but that's not surprising, it probably takes several years to enjoy A4000 with a performance advantage.

What We've Learned

So you have it, in short the Nvidia RTX A4000 behaves very similarly to the GeForce RTX 3060 Ti, which might make it a convenient convertible option based on price and availability in your area. In Australia, the A4000 for players priced at A$2,000 doesn't make sense for the current listings. That's because the RTX 3060 Ti can easily be bought for AU$1,250, while you'll pay around AU$2,000 for the RTX 3070 Ti.

For gamers, the only possible advantage of the A4000 is much more memory. That's too little for you now, while the faster 3070 Ti memory gives you better worldwide performance with more cores.

Another advantage of the A4000 is its performance, but this advantage for gaming is due to the single-slot cooling that makes the A4000 a taller and warmer product out the window. Out. Gamers also don't pay much attention to performance, and if you do, you can get a low-voltage GeForce graphics card. Your hands are tied with this, at the moment I don't think there is a water block for the A4000, but if someone finds a way to remove the voltage lock, that would be a really fun experience. Although it's worth noting that the VRM is designed for a 140W configuration, it may not have as much power to achieve the same performance as the 3070. Anyway, for now, it looks like you can only pay 10% more from A4000.

It should be noted that all GeForce RTX features such as DLSS, Reflex, Radiation Tracking, DSR, Shadowplay and Nvenc are all supported and work with the A4000, just like the GeForce GPU. Nvidia has several different categories of drivers. We installed the production/studio driver and it worked fine in the games tested for this article and performance remained the same, as did the new Feature Branch driver. You can install GeForce Experience manually to access GeForce features, and everything works fine with these drivers.

Shall we consider buying an RTX A4000 over an RTX 3070 for gaming? And if so, how much more does the A4000 cost? We're definitely considering buying it, but we're not doing it at a premium. So the A4000 will likely cost between the 3060 Ti and the 3070 Ti, perhaps very close to the 3060 Ti.
