Nvidia GeForce RTX 4070 review: Highly efficient 1440p gaming

Finally, Nvidia’s 70-class GeForce graphics cards get more than 8GB of memory. And finally, there’s a member of the RTX 40-series possibly worth buying other than the $1,600 flagship. Meet the 12GB GeForce RTX 4070. It’s hitting the streets for $599 on April 13.

The GeForce RTX 4070 delivers exceptionally fast 1440p gaming performance while sipping power, a combination that let Nvidia create an adorably tiny Founders Edition version of the GPU. Those frame rates climb even higher in games that support Nvidia’s DLSS upscaling technology, and astronomically higher in games embracing DLSS 3 Frame Generation—even with ray tracing flipped on. Exceptional software features like Nvidia Broadcast, Reflex, and RTX Video Super Resolution help sweeten the pot.

The RTX 4070 may be worth considering but it’s not a slam-dunk recommendation. Paying $599 for a 70-class graphics card explicitly marketed for 1440p gaming deeply aches, especially when Nvidia made technical decisions that actively hurt the GPU’s 4K gaming prowess. We’d also like to see 16GB of memory in a $600 graphics card in 2023. Still, while the RTX 4070 costs $100 more than its predecessor, it’s nowhere near as insultingly overpriced as the $800 RTX 4070 Ti and $1,200 RTX 4080 are.

With those broad-strokes impressions out of the way, let’s dig into the details.

What are the GeForce RTX 4070’s specs?

Nvidia’s $599 GeForce RTX 4070 uses a cut-down version of the 4N “Ada Lovelace” AD104 GPU found in the RTX 4070 Ti. Here’s a look at its core specifications:

• Graphics Processing Clusters: 4
• Texture Processing Clusters: 23
• Streaming Multiprocessors: 46
• CUDA Cores: 5888
• Tensor Cores: 184 (4th Generation)
• RT Cores: 46 (3rd Generation)
• Texture Units: 184
• ROP Units: 64
• Base Clock: 1920MHz
• Boost Clock: 2475MHz
• Memory Clock: 10500MHz
• Memory Data Rate: 21Gb/s
• Total Video Memory: 12GB GDDR6X
• Memory Interface: 192-bit
• Total Memory Bandwidth: 504GB/s
• Transistor Count: 35.8 billion
• Connectors: 3x DisplayPort, 1x HDMI
• Power Connectors: 2x PCIe 8-pin cables (adapter in box) OR 300W or greater PCIe Gen 5 cable
• Power Supply Required:650W

This all represents solid advances over the technology inside last generation’s $499 RTX 3070 and $599 RTX 3070 Ti, though it’s a significant step back from the 4070 Ti’s might—that card runs roughly 15 to 25 percent faster, depending on the game and resolution. The performance gap widens slightly at 4K resolution.

You don’t really want the GeForce RTX 4070 for 4K gaming anyway—a conclusion that’s supported by Nvidia’s decision to market this GPU around playing games at 100 frames per second at 1440p resolution. As we discussed extensively in the RTX 4070 Ti’s review, Nvidia equipped the AD104 GPU used by both 4070 cards with a surprisingly narrow 192-bit memory bus, which constrains overall memory bandwidth. The RTX 4070 comes with GDDR6X, faster memory than its predecessor, as well as a much larger L2 cache (36.8K) for keeping more tasks on the GPU itself. Both of those help boost memory performance but I wouldn’t buy this card for 4K gaming—only 1440p.

By contrast, the RTX 3080—which, again, was a higher-tier card that cost $100 less than the 4070 Ti—wielded a 320-bit bus, which is typical for a high-end GPU. Even the already-pandemic-overpriced $600 RTX 3070 Ti had a 256-bit bus. You had to go all the way down to the $330 RTX 3060 to find an Nvidia GPU with a 192-bit bus last generation.

That goes doubly so given its 12GB memory capacity—a very welcome upgrade over the 8GB that Nvidia’s 70-class remained stuck on since the GTX 1070’s launch in 2016. That said, with games gobbling ever-increasing amounts of VRAM now that the latest console generation (and 16GB of shared memory) are the standard, I’d be nervous about buying a graphics card for 4K gaming with less than 16GB of memory. The RTX 4070’s 12GB should be fine for most games at 1440p, though note that flipping on ray-tracing effects eats heavily into VRAM as well.

This is a tremendously energy-efficient graphics card, which let Nvidia craft a smaller, totally adorable dual-slot version of its Founders Edition board. Nvidia’s fantastic-looking FE designs treat almost every part of the card as a heatsink and utilize unorthodox flow-through fan cooling. That all holds true with the RTX 4070 FE—it’s just so much smaller than its triple-slot siblings. This beast will be popular in high-end small form-factor gaming builds.

Nvidia equipped the RTX 4070 Founders Edition with a single HDMI 2.1 port as well as three DisplayPort 1.4a connections. It also uses the new 16-pin 12VHPWR connector despite its relatively modest power demands—you only need a 650W supply—so be prepared to look at the unsightly too-short adapter plugs in your case if you don’t want to invest in a new ATX 3.0 power supply (or at least custom 12VHPWR cords). FE cards don’t include extra features like dual-BIOS switches or customizable RGB lighting.

As an RTX 40-series “Ada Lovelace” graphics card, the GeForce RTX 4070 also supports Nvidia’s staggering arsenal of features, including DLSS, DLSS 3 Frame Generation, Nvidia Broadcast, RTX Video Super Resolution, superb ray-tracing prowess, Nvidia Reflex, and more. Nvidia’s software stack is a major feather in its cap. It’s worth noting that while the RTX 4070 supports AV1 encoding, new to GeForce this generation, product manager Justin Walker told me the 4070 only includes a single AV1 encoder rather than the pair found in higher-priced RTX 40-series offerings.

Got it? Good. Let’s get to the benchmarks.

Our test system

We test graphics cards on an AMD Ryzen 5900X PC used exclusively for benchmarking GPUs. We now test with PCIe Resizable BAR (also known as Smart Access Memory on Ryzen systems) active, as most modern gaming PCs released in the last four years support the performance-boosting feature, either natively or via a motherboard firmware update. Nvidia also recommends turning on the optional “Hardware-accelerated GPU scheduling” option in Windows to let the RTX 40-series stretch its legs to the fullest, so we’ve made that tweak as well. Most of the hardware was provided by the manufacturers, but we purchased the storage ourselves.

• AMD Ryzen 5900X, stock settings
• AMD Wraith Max cooler
• MSI Godlike X570 motherboard
• 32GB G.Skill Trident Z Neo DDR4 3800 memory, XMP active
• Corsair HX1500i power supply (and optional $20 12VHPWR 600 cable for Nvidia GPUs)
• 1TB SK Hynix Gold S31 SSD x2

We test a variety of games spanning various engines, genres, vendor sponsorships (Nvidia, AMD, and Intel), and graphics APIs (DirectX 9, 11, DX12, and Vulkan), to try to represent a full range of performance potential. Each game is tested using its in-game benchmark, sanity checked by Nvidia’s FrameView tool, at the highest possible graphics presets unless otherwise noted, with VSync, frame rate caps, real-time ray tracing or DLSS effects, and FreeSync/G-Sync disabled, along with any other vendor-specific technologies like FidelityFX tools or Nvidia Reflex. We’ve also enabled temporal anti-aliasing (TAA) to push these cards to their limits.

We run each benchmark at least three times and list the average result for each test. Outside of esports, we’ve limited our benchmarks to 4K and 1440p resolutions, as those are the natural fits for these juggernaut GPUs (despite the 4070 Ti’s paltry bus width). We test features like ray tracing and DLSS in a separate section, as upscaling features like DLSS and AMD’s rival FSR tweak the look of games to help them run faster.  

We’re going to show these benchmarks without individual game commentary. In addition to paying attention to how the RTX 4070 performs in relation to the 4070 Ti, 3080, and 3070, also note how it compares against AMD’s Radeon RX 6800 XT and 6900 XT—two last-generation models that are faster and more memory-packed than Nvidia’s new offering, and can often be found for less on the street. Nvidia’s GPUs womp in ray tracing and extra features, though they lag behind Radeon in raw esports frame rates.

How is the RTX 4070’s ray tracing and DLSS performance?

In addition to traditional gaming tests, we separately benchmark how graphics cards perform with ray tracing enabled at the highest possible settings (though we stick to U
