RTX 3080 12GB vs RX 9070 GRE for Gaming: Which Is Better?

For a new build, the RX 9070 GRE is the better pick: it lands in roughly the same performance class as the RTX 3080 12GB in rasterized games while using about 130 W less power and adding FSR 4 and a warranty. The RTX 3080 12GB is worth choosing only as a clearly cheaper used card, or if you rely on DLSS and CUDA applications and want stronger heavy ray tracing at 4K thanks to its huge memory bandwidth.

Same VRAM, Very Different Designs

Both cards carry 12 GB of VRAM, but they reach their performance in opposite ways. The RTX 3080 12GB, released in January 2022 at $799, is a big Ampere chip with a 384-bit bus and 912.4 GB/s of GDDR6X bandwidth. The RX 9070 GRE, released in May 2025 and listed at $549, is a compact RDNA 4 design with a 192-bit bus, 432.0 GB/s of GDDR6 bandwidth and 48 MB of Infinity Cache. One brute-forces with bandwidth and power; the other leans on cache and efficiency.

Spec Sheet

How the Performance Stacks Up

What reviews and aggregates say

No major outlet has run a direct RTX 3080 12GB versus RX 9070 GRE review, and the available aggregate data disagrees. HowManyFPS’ average across more than 100 games puts the GRE about 18 percent ahead, and 3DMark Time Spy scores also favor the GRE by a similar margin. Technical City’s aggregate instead rates the RTX 3080 12GB about 13 percent faster overall. Launch coverage, including Wccftech’s review roundup, placed the RX 9070 GRE roughly on par with the older RX 7900 GRE and a little behind the RTX 5070.

Reading these together, the honest conclusion is that the two cards are in the same broad class, with results swinging by game and resolution. The GRE tends to look better at 1080p and 1440p in modern raster titles; the RTX 3080 12GB tends to close the gap or pull ahead at 4K, where its 912 GB/s of bandwidth matters most.

Typical frame rates

At 1440p high settings in demanding recent games, both cards commonly land somewhere around 60 to 110 FPS, depending heavily on the title, CPU and game version. At 4K, both generally need upscaling to hold 60 FPS in heavy games.

Ray tracing

In 3DMark Speed Way, a ray tracing benchmark, published scores show the RTX 3080 12GB about 18 percent ahead. RDNA 4 dramatically improved AMD’s RT performance compared with older Radeon generations, so in lighter RT games the GRE is competitive. In heavy RT and path tracing, especially at higher resolutions, the Ampere card usually holds an edge.

Upscaling and Frame Generation

• RTX 3080 12GB: supports DLSS 4 Super Resolution with the transformer model and Ray Reconstruction. It does not support DLSS Frame Generation, which needs RTX 40 or newer, but it can use FSR frame generation in games that offer it.
• RX 9070 GRE: supports FSR 4, AMD’s machine-learning upscaler exclusive to RDNA 4, plus FSR frame generation. FSR 4 is a large quality improvement over FSR 3.

DLSS remains available in a larger number of games. FSR 4 is newer but covers many recent releases. For frame generation, the GRE has AMD’s native solution, while the 3080 relies on FSR or XeSS frame generation where supported.

Electricity and Heat: A Worked Example

The RTX 3080 12GB is rated 130 W higher than the RX 9070 GRE. At 20 hours of gaming a week, that is 130 W x 1,040 hours = about 135 kWh per year. At $0.15 per kWh, the 3080 costs roughly $20 more per year to run, and puts noticeably more heat into your room during summer gaming sessions. Over three years, that adds around $60 to the effective price of a used 3080 12GB.

PSU Requirements and Connectors

Using GPU TDP + CPU gaming draw + about 150 W headroom:

• RTX 3080 12GB: 350 W + about 150 W + 150 W = roughly 650 W. Ampere cards can produce sharp transient spikes, so a quality 750 W to 850 W unit is the safer choice.
• RX 9070 GRE: 220 W + 150 W + 150 W = roughly 520 W. A good 650 W supply leaves comfortable headroom.

The spec database lists a 12-pin connector for the RTX 3080 12GB, but partner cards commonly use two or three 8-pin inputs, so check the exact model and your PSU’s available cables. The GRE uses two standard 8-pin connectors.

Case Clearance

The listed RTX 3080 12GB length is 285 mm in a 2-slot form, but many partner versions are larger triple-fan, 2.5- to 3-slot designs exceeding 300 mm. The RX 9070 GRE ships only in partner designs, so length varies; many are in the 2-slot to 2.5-slot range. Measure your case before choosing, especially in compact mid-towers.

Price per Frame

Treat both as roughly equal performance, 100 points each, given the conflicting data:

• Launch MSRP: RTX 3080 12GB at $799 = $7.99 per point; RX 9070 GRE at $549 = $5.49 per point.
• Used RTX 3080 12GB: usually around $350 to $450. At $400 it costs $4.00 per point, cheaper than a new GRE.

Add the roughly $20 per year in extra electricity and the lack of warranty, and a used 3080 12GB needs to sell for about $100 or more below a new GRE to be the better deal.

Picking Between Them

Driver Support and Longevity

The RX 9070 GRE is a current-generation card, so it receives AMD’s full game-ready driver attention, including new FSR 4 game integrations as they arrive. NVIDIA continues to support Ampere with regular drivers and DLSS updates, and the 3080 12GB benefits from DLSS 4’s transformer model, which noticeably improves upscaled image quality over older presets. Neither card is at risk of losing support soon.

Longevity is more about features than drivers. The 3080 12GB will never gain DLSS Frame Generation, and its 350 W rating makes it the less attractive card to keep for many more years in a hot room or small case. The GRE’s newer architecture, PCIe 5.0 interface and native frame generation support give it a modest edge in staying relevant, even though both share the same 12 GB memory ceiling that will eventually limit high-texture settings.

Used RTX 3080 12GB Checklist

Many 3080-class cards were used for mining in 2021 and 2022. GDDR6X memory runs hot, so check memory junction temperatures during a stress test, listen for fan bearing noise, and ask whether thermal pads were replaced. Confirm the card’s power connector type matches your PSU before purchase.

Frequently Asked Questions

Is the RX 9070 GRE faster than the RTX 3080 12GB?

They are in the same performance class, and sources disagree on the winner. Some aggregates put the GRE about 18 percent ahead in modern games, while others favor the 3080 12GB by around 13 percent. Expect the GRE to do relatively better at 1080p and 1440p, and the 3080 to do better at 4K.

Which card is better for ray tracing?

The RTX 3080 12GB generally has an edge in heavy ray tracing, as reflected in 3DMark Speed Way results. RDNA 4 made the GRE competitive in lighter RT workloads. Path tracing still favors NVIDIA.

Does the RTX 3080 12GB support DLSS Frame Generation?

No. DLSS Frame Generation requires RTX 40 or RTX 50 hardware. The 3080 12GB supports DLSS 4 Super Resolution and can use FSR frame generation in supported games.

What PSU do I need for each card?

A quality 750 W to 850 W unit is recommended for the RTX 3080 12GB due to its 350 W rating and power spikes. The RX 9070 GRE runs well on a good 650 W supply with two 8-pin connectors.

Is 12 GB of VRAM enough on both?

For 1440p, 12 GB covers most current games. A few titles exceed it at maximum textures with ray tracing. Both cards share this limit, so neither has a VRAM advantage.
