Introduction

AMD has now launched its Radeon RX 6600 XT graphics card, a mid-range Navi 23-based GPU that also packs 8GB of GDDR6 memory and 32MB of Infinity Cache: aimed at 1080p gaming.

MSI sent over their new Radeon RX 6600 XT GAMING X graphics card, so you should know what to expect at this point: a custom Radeon RX 6600 XT infused with MSI's herbs and spices with its TWIN FROZR 8 thermal design.

The look and style of the MSI Radeon RX 6600 XT GAMING X doesn't look much different to the MSI Radeon RX 6700 XT GAMING X from the outside, except for it's a big smaller and there are slight tweaks -- the biggest of which is that the new RX 6600 XT GAMING X requires just a single 8-pin PCIe power connector.

AMD's new Radeon RX 6600 XT is being aimed at a competitor to the GeForce RTX 3060, and beats it, while losing to the higher-end GeForce RTX 3060 Ti and GeForce RTX 3070. It's uniquely positioned, and if sold at MSRP of around $379-$449 or so... they'd be great 1080p cards.

Take the price away, and consider it consumes under 150W of power and the MSI Radeon RX 6600 XT GAMING X runs at just 60C under load and you have an exciting little pocket rocket GPU.

Everything You Need to Know About The RX 6600 XT

AMD's new Radeon RX 6600 XT is everything we've come to know and love about the Radeon RX 6000 series graphics cards: we have the kick-ass RDNA 2 architecture, 8GB of GDDR6 memory, Infinity Cache, HDMI 2.1 connectivity, FidelityFX Super Resolution (FSR), ray tracing, and everything in between.

MSI Radeon RX 6600 XT GAMING X Review 07 | TweakTown.com

The new Radeon RX 6600 XT has 8GB of GDDR6 memory clocked at 16Gbps on a 128-bit memory bus with 32MB of AMD Infinity Cache (down from the 128MB on the higher-end Radeon RX 6800 XT for example). Infinity Cache helps the Radeon RX 6600 XT swing above its weight, especially when compared with previous-gen GPUs in the same "price range" as the RX 6600 XT.

AMD is marketing its new RDNA 2-powered Radeon RX 6600 XT graphics card up against NVIDIA's previous-gen Pascal-based GeForce GTX 1060 and showing that it has far over 100%+ performance gains in the latest titles. This is a huge deal for gamers that have a GTX 1060 or RX 5x0 series graphics card, and want an RDNA 2-powered upgrade... the Radeon RX 6600 XT is a fantastic option for 1080p gamers.

Hell, the Radeon RX 6600 XT is even capable of beating NVIDIA's new Ampere-powered GeForce RTX 3060 graphics card, but not the GeForce RTX 3060 Ti -- we'll have more on that later, but AMD has positioned the new RX 6600 XT very well in the performance department.

Add into the fact you've got FSR support -- at least in the small amount of games available now, is another nice touch for the Radeon RX 6600 XT.

I've got a new upgrade inside of my GPU test bed before my change to a next-gen test bed, where I will be preparing for NVIDIA's next-gen Ampere graphics cards and AMD's next-gen RDNA 2 graphics cards.

MSI Radeon RX 6600 XT GAMING X Review 1162 | TweakTown.com

Sabrent helped out with some new storage for my GPU test beds, sending over a slew of crazy-fast Rocket NVMe PCIe M.2 2280 SSDs. I've got this installed into my GPU test bed as the new Games Storage drive, since games are so damn big now. Thanks to Sabrent, I've got 2TB of super-fast M.2 PCIe 3.0 x4 SSD storage now.

Middle-earth: Shadow of War is a sequel to the popular Shadow of Mordor, which was powered by the Lithtech engine. When cranked up to maximum detail, it will chew through your GPU and its VRAM like it's nothing.

1080p Benchmark Performance Thoughts

Fantastic performance across the board from AMD with their new Radeon RX 6600 XT killing it in Assassin's Creed: Valhalla with 83FPS average at 1080p. This is beating the GeForce RTX 3070 Ti at this point, but it is a Radeon-friendly title.

Shadow of War is more punishing, knocking the RX 6600 XT Down to "just" 127FPS average -- losing to the previous-gen RX 5700 XT and GTX 1080 Ti. Metro Exodus has the RX 6600 XT matching the RX 5700 XT with 53FPS average.

Fantastic performance at 1080p for a card that consumes less than 150W.

1440p Benchmark Performance Thoughts

I wouldn't recommend AMD's new Radeon RX 6600 XT for 1440p gaming, but if the game is right -- like for example, Assassin's Creed: Valhalla -- then you're pulling 60FPS average at 1440p. Not too damn bad at all, AMD.

Shadow of War still cranks along at 88FPS average, while Shadow of the Tomb Raider gives you 102FPS average at 1440p. Next-gen console crushing performance, even at 1440p.

4K Benchmark Performance Thoughts

Please don't buy the Radeon RX 6600 XT thinking you're going to be blazing through games at 120FPS at 4K... but hell, 33FPS average in Assassin's Creed: Valhalla at 4K? Nice.

Power Consumption & Temps

MSI's custom Radeon RX 6600 XT GAMING X was running at around 2600-2654MHz GPU boost out of the box, which gives it that edge against the XFX Radeon RX 6600 XT Speedster MERC 308 Black which was hitting a ceiling of 2605MHz GPU boost.

What's Hot, What's Not

What's Hot

  • MSI's custom GAMING X style: I've always been a fan of the MSI style with its TWIN FROZR 8 cooler looking great on the MSI RX 6600 XT GAMING X graphics card.
  • TWIN FROZR 8 thermal solution: Not only does the style of the TWIN FROZR 8 cooler look great, but my god it is impressive in terms of keeping that Ampere GPU + 8GB of GDDR6 memory cool.
  • Sub 60C gaming: 60C gaming... yeah, that is impressive.
MSI Radeon RX 6600 XT GAMING X Review 511 | TweakTown.com
  • 8GB GDDR6 memory: Good to see 8GB of GDDR6 here, AMD could've gone a little cheaper and offered 6GB but we don't have that. 8GB of GDDR6 memory is here on the Radeon RX 6600 XT which is more than enough for 1080p gaming.
  • 1080p powerhouse GPU: Speaking of 1080p gaming, you've got enough performance to drive 60FPS in AAA titles and 120FPS+ in esports and other games like Overwatch, League of Legends, Rocket League, CS:GO, Valorant, and others.
  • Mid-range Big Navi power: Big Navi is flexing muscle up and down the GPU chain, from the lofty heights of the Radeon RX 6900 XT graphics card -- right down to the Radeon RX 6600 XT. AMD's new RDNA 2 architecture shows that it can spread across many products -- including consoles -- right down to the Radeon RX 6600 XT and maintain fantastic performance.

What's Not

GPU shortages, price gouging, MSRP lels, blah, blah, blah.

You know what you're getting here with the MSI RX 6600 XT GAMING X, there's not that much to hate here apart from the insane GPU pricing right now that is not limited to just MSI, Radeon, NVIDIA, or any other brand.

Final Thoughts

MSI's new Radeon RX 6600 XT GAMING X graphics card is an impressive kit, and while you've got performance that you'd never tell the difference between another custom RX 6600 XT -- what you do have here is the excellent TWIN FROZR 8 thermal solution.

MSI Radeon RX 6600 XT GAMING X Review 504 | TweakTown.com

If you compare the new Radeon RX 6600 XT up against the previous-gen Radeon RX 5600 XT, it's simply smashing -- up against the even older and marketed-like-hell Radeon RX Vega 64... then the RDNA 2 architecture really shines. 1080p gaming performance is great across the board, 60FPS+ in AAA titles and 120FPS+ in plenty of esports titles.

MSI keeps things nice and chill at around 60C on the GPU, and that's through many hours of benchmark torture and rounds of Call of Duty: Warzone. MSI shines through with its Radeon RX 6600 XT GAMING X, offering the tweaked TWIN FROZR 8 thermal solution.

If you want to go to Team Green, then MSI offers its GeForce RTX 3060 GAMING with the same TWIN FROZR 8 cooler. If you want to try out Team Red, the new MSI Radeon RX 6600 XT GAMING X is here for those that want some of that 7nm RDNA 2 goodness in their gaming PC.

AMD might not have caught your eye with the first-gen RDNA-based Radeon RX 5000 series, but if you waited for the Radeon RX 6000 series and wanted to spend under $500 -- well, under "$500" in this New World of graphics card prices then the new MSI Radeon RX 6600 XT GAMING X is a mighty fine offering.

Most of all, MSI has the performance crown right now -- I just came in from reviewing the XFX Radeon RX 6600 XT Speedster MERC 308 Black and it beats it... just, by just a few FPS here and there. Bt that's enough to make the MSI RX 6600 XT GAMING X stand out.
