Expert Reviews For Nvidia GTX 1660

By PCGamer
The GeForce GTX 1660 continues the downward price and performance trend with Nvidia’s Turing architecture, cutting additional high-end features to bring a generational improvement to the mainstream market.

By AnandTech
As for NVIDIA’s loyal opposition, the launch of the GTX 1660 will continue to put pressure on AMD’s aging Polaris video cards. The GTX 1660 is faster than all of them – including the fastest RX 590 – so AMD and its board partners will have little choice but to cut prices. This means AMD can try to position their cards as spoilers to the GTX 1660 – and $219 RX 590 cards are already popping up – but they can’t take on NVIDIA in terms of performance or power efficiency. AMD will have an edge in pack-in bundles though, as they’re continuing to offer their Raise the Game Bundle, which for the RX 590 is the full, 3 game pack.

By PCGamesN
The new GTX 1660, especially in this overclocked trim, is now the best ~$200 graphics card around… so long as it retains this launch pricing. It outperforms the RX 590 and is priced to compete with the RX 580. But as an upgrade for anyone on mainstream GPUs of the last generation it might not be the card for you.

By HotHardware
 It seems that Gigabyte is going after new system builders with their card that will likely use the latest display standards, while EVGA is also catering to potential upgraders that may have a GTX 960-class card and monitor with an older DVI connector.

By RockPaperShotgun
I should note that AMD’s free games bundle only lasts until April 6th 2019, though, so depending on what they follow it up with (if anything at all), then the GTX 1660 may well regain its crown as the ultimate graphics card for £200 / $220. Until then, however, the value proposition offered by the RX 590 is almost too good to pass up.

Expert Reviews For AMD Radeon RX 580

By LiveAtPC
A gaming card that looks cool while keeping cool and pumping out polygons like no tomorrow.

The RX 580 from Gigabyte is a fantastic bang-for-your-buck GPU. The high-end cards from the top manufacturers usually perform similarly, so buying designs usually come down to aesthetics, software, warranty, etc. Given this situation the Aorus is certainly a great GPU that is well-built, has aggressive looks with great lighting, and performs well while being whisper-quiet at all times, even under full load. Good luck finding one for MSRP though.

By Play3r
A strange amalgamation of high-end features and looks tied down by a mainstream GPU option and a weak lid. The current iteration of the Legion Y730 could use an update sooner rather than later in regards to its chassis rigidity and GPU options.

By ProLockers
We do know that GPUs are currently extremely difficult to get hold of due to this insane mining craze that’s going on, but if you were to buy a card… it really is a toss up between this and the GTX 1060, be it a STRIX model or something else. As Gavin clearly stated, if you can grab yourself an RX 480 for cheaper, you may as well go ahead and do that. If you can’t, then this one will suit you just fine as well.

By Gadgets360
If you need a graphics card to show off and aren’t willing to spend on a flagship-class GPU, the Strix Radeon RX 580 will satisfy you. If it’s going to stay hidden away in a windowless cabinet, save a bit of money and go with a less flashy model.

By TechAdvisor
The Asus ROG Strix Radeon RX 580 TOP Edition 8GB is one of the most expensive Radeon RX 580 cards available, but offers excellent performance delivering similar overall frame rates to an overclocked Nvidia GTX 1060, although this will of course depend on which games you play. The board offers superb build quality and a great selection of features including programmable lighting effects and bundled overclocking software. It’s sheer size may be a problem for some smaller cases, however, and audible coil whine can occasionally spoil the experience.

By TechRadar
Undoubtedly this isn’t the card we expected AMD to launch right now. The RX 580, is no Titan killer, nor does it change the GPU ecosphere in any meaningful way, however it just slips in, taking back that value crown, away from Nvidia’s GTX 1060.

By NotebookCheck
Those who do not want an Nvidia GPU and are on the lookout for a good graphics card that costs no more than 300 Euros (~$344) will not be disappointed with the Asus ROG Strix Radeon RX 580. Besides the good cooling solution, the GPU also features eye-catching RGB effects.

  • Not substantially different from the RX 480
  • Uses more power than Nvidia’s equivalent GTX 1060 6GB

Detailed Review and Comparison:

Above we have showed the overview and depth specifications of both the graphics card. Now, we are sharing the full review and in-depth comparioson of both graphics card.

QUICK SPECS: GTX 1660 vs RX 580

GTX 1660

RX 580

Released: March 2019 Released: April 2017
1.408 Cuda Cores 2.304 Stream Processor
1.530MHz Base Clock 1.257MHz Base Clock
1.785MHz Boost Clock 1.340MHz Boost Clock
6GB GDDR5 Memory 8GB GDDR5 Memory
8GBPS Memory Speed 8GBPS Memory Speed
192-BIT Memory Interface 256-BIT Memory Interface
Memory Bandwidth 192GB/S Memory Bandwidth 256GB/S

Let’s take a look specs, note that things like Cuda cores and stream processors are not directly comparable, even clock speeds aren’t too comparable here given both are different architectures. Something to take note of though is that 1660 has 6GB of GDDR5 memory, while the 580 has 8GB, so we may see that additional memory comes in use at higher resolutions with higher settings in some titles. The 580 is also available in the lower tier 4GB model, however, we’re not looking at that here.

OVERVIEW: GTX 1660 vs RX 580

The first thing I want to talk about the aesthetics of these cards. Now the reason I want to start with aesthetics because there’s not much to say and honestly unless you’re mounting your card vertically in your system you’re probably not gonna see much of it. But there are a few things that I wanted to touch on with both of these cards that I do and don’t like.

First up on the GTX 1660, I really like the color scheme way that they have. I love the color in the design on the fan. Now I don’t understand, why it’s such a short card with a three-slot design, especially when they’re only using one slot for the I/O, It has massive fans for cooling.

Now comparing to the RX 580, the version I picked up from gigabyte, does have these orange lines on it. One thing that I do love about this card that if you do have LED lights in your system you do have RGB here on this side that you can too with the software to match the other colors in your system. Overall I’m not too mad at this one at all but I do prefer to GTX 1660.


Obviously you want to have good temperatures for the longevity of your components, so that they stay healthy, overheating, and things like that. I’ve done a few videos on this specific RX 580. I have some issues with temperatures and fan noise, not so much that this will get really hot but I could hear the fans noise, it’s just spinning loudly under load. For the most part, it didn’t bother me much. I want to give a tip – changing the thermal paste regularly will lower the sound of fans. On the other hand, GTX 1660 was very good at temperatures, compared to RX 580. And there was minimal fan noise.


For the testing, I’m using the Zotac Geforce GTX 1660 6GB and Gigabyte Radeon RX 580 Gaming graphics cards. The system that I’m testing with has an Intel i7-8700K CPU overclocked to 5.0GHz in an MSI Z390 Gaming Pro Carbon motherboard, along with 16GB of T-Force Night Hawk CL16 memory from Team Group running at DDR4-3200 in dual channel. The same Windows updates and game updates were used, and Nvidia 419.35 drivers were used for 1660 while Adrenaline 19.3.2 drivers were used for the 580, the newest from both Nvidia and AMD at the time of testing, so let’s get into the results. Note- All games are tested at 1080p and FPS shown are Average.


GTX 1660 vs RX 580 - Control

Let’s start out Control, which was tested with all settings maxed out. In terms of average FPS 1660 was 9% ahead of the 580.

Resident Evil 2 Remake

World War Z was tested with the Ulletical FPS benchmark, and both cards were delivering very high frame rates as usual. The GTX 1660 was just 1% ahead of RX 580.

Battlefield V

GTX 1660 vs RX 580 - Battlefield V

Battlefield 5 was tested in campaign mode rather than multiplayer, as it’s easier to consistently reproduce the test run. I found both cards to deliver a playable experience with high settings, with the 1660 just 2.9% behind.

Assassin’s Creed Odyssey

GTX 1660 vs RX 580 - Assassin's Creed Odyssey

Assassin’s Creed Odyssey was tested with the built in benchmark using high settings, and the 1660 was coming out ahead here, almost 11% faster in terms of average frame rate over the 580.

Metro Exodus was tested with the built-in benchmark at high settings. GTX 1660 was 11.6% ahead of the 580.

Strange Brigade

Strange Brigade was tested with the built-in benchmark using Vulkan with Async compute enabled maxed out at ultra settings. This was an interesting result, as expected the 580 will win here. In terms of average FPS, GTX 1660 was only 2% behind.

Far Cry New Dawn

GTX 1660 vs RX 580 - Far Cry New Dawn

Far Cry New Dawn was tested using the built in benchmark with high settings, and the 1660 was ahead in all regards this time. You are looking at almost a 13% improvement to average frame rate.

Wolfenstein Youngblood

GTX 1660 vs RX 580 - Wolfenstein Youngblood

Wolfenstein Youngblood was tested using the built in benchmark at high settings. The 1660 was 12% ahead of the 580.

GTX 1660 vs RX 580 - Tomb Raider

Shadow of the Tomb Raider was also tested using the built in benchmark with high settings. At 1080p the GTX 1660 was 13.4% ahead of the 580.

WHICH TO BUY: GTX 1660 or RX 580

Personally I don’t think I’d have any issues picking either of these, they seem like decent options for the money so I think it comes down to what level of performance you’re after as to whether or not the extra $30-50 is worth spending on GTX 1660.
