RTX 5070 vs RTX 5080: Performance and Value Compared

Spec sheet comparison: RTX 5070 vs RTX 5080

The RTX 5070 and RTX 5080 are both part of NVIDIA's GeForce RTX 50 Series, built on the Blackwell architecture. They share the same generation of features, including DLSS 5, fifth-generation Tensor Cores, and fourth-generation Ray Tracing Cores, but they differ significantly in raw specifications.

According to NVIDIA's official specifications, the RTX 5080 has 10,752 CUDA cores, while the RTX 5070 has 6,144. The RTX 5080 also comes with 16GB of GDDR7 memory on a 256-bit interface, delivering 960 GB/sec of memory bandwidth. The RTX 5070 has 12GB of GDDR7 on a 192-bit interface, with 672 GB/sec of bandwidth.

Both cards support the same display outputs: three DisplayPort connectors and one HDMI, and both can drive up to four monitors. They also share the same maximum digital resolution of 4K at 480Hz or 8K at 165Hz with DSC, so your choice of monitor is not limited by either card.

Understanding the performance gap

The performance gap between the RTX 5070 and RTX 5080 comes down to three main factors: CUDA core count, memory bandwidth, and memory capacity. The RTX 5080 has roughly 75% more CUDA cores than the RTX 5070, which directly translates to higher compute throughput for rendering and AI tasks. Its memory bandwidth is also about 43% higher, which helps when pushing large textures at high resolutions.

For gaming, this means the RTX 5080 is better equipped for 4K resolution and high-refresh-rate monitors, where the GPU must process more pixels and larger texture data. The RTX 5070, with its 12GB of memory and 192-bit bus, is more aligned with 1440p gaming, where it can handle most titles without running into memory limits.

NVIDIA's own relative performance charts place the RTX 5070 against the RTX 4070 at 1440p with max settings, while the RTX 5080 is compared to the RTX 4080 at 4K. This indicates the intended resolution tiers for each card, but the actual experience depends on the specific game and settings.

DLSS and AI features: what both cards share

Both the RTX 5070 and RTX 5080 support the full suite of DLSS 5 features, including 3D-Guided Neural Rendering, Dynamic Multi Frame Generation, Frame Generation, Ray Reconstruction, and Super Resolution. This means you get the same AI-powered upscaling and frame generation capabilities on either card, which can significantly boost performance in supported games.

The Tensor Cores on both cards are fifth-generation, but the RTX 5080 offers nearly double the AI TOPS (1,801 vs 988), which may lead to faster processing of AI workloads, though this is not a direct measure of gaming performance. For gaming, the DLSS features are the same, so the choice between the two cards is more about raw rasterization power and memory.

Both cards also support NVIDIA Reflex Low Latency Mode and Reflex Frame Warp (coming soon), which are important for competitive play. If you play fast-paced shooters, either card will give you access to these latency-reducing features, but the higher frame rates from the RTX 5080 could provide a slight edge in responsiveness.

Streaming and encoding capabilities

For streamers, both the RTX 5070 and RTX 5080 include the ninth-generation NVIDIA Encoder (NVENC), which offloads video encoding from the CPU. This is crucial for streaming while gaming on a single PC, as it frees up system resources for the game itself.

The RTX 5080 has two ninth-generation NVENC encoders, while the RTX 5070 has one. This means the RTX 5080 can handle more simultaneous encoding tasks, which could be beneficial if you stream to multiple platforms or record at high bitrates. However, for most streamers, a single encoder is sufficient.

Both cards support AV1 encoding, which provides better image quality at lower bitrates compared to older codecs. This is a key feature for streaming, as it allows for higher-quality broadcasts without consuming excessive bandwidth. The NVIDIA Broadcast app, which uses AI to remove background noise and improve webcam quality, is also available on both cards.

Value and tier: which card fits your setup

The RTX 5070 is positioned as a 1440p gaming card, offering a balance of performance and cost. With 12GB of GDDR7 memory, it is well-suited for modern titles at 1440p with high settings, and it can handle 4K in less demanding games or with DLSS enabled. Its lower power draw and smaller footprint make it a good fit for mid-range builds.

The RTX 5080 is a 4K gaming card, designed for those who want maximum performance at high resolutions and refresh rates. Its 16GB of memory and higher bandwidth provide headroom for future titles and for games that use large texture packs. It is also a better choice for multi-monitor setups or for those who want to play at 4K with ray tracing enabled.

When deciding between the two, consider your monitor resolution and refresh rate. If you play at 1440p with a 144Hz or 240Hz monitor, the RTX 5070 is likely sufficient. If you have a 4K monitor or plan to upgrade to one, the RTX 5080 offers the performance needed to take full advantage of it. The RTX 5080 also provides more future-proofing, as games continue to demand more memory and processing power.

What to pick for your play

Questions

Is the RTX 5080 worth the extra cost over the RTX 5070?

The RTX 5080 offers significantly more CUDA cores, double the memory bandwidth, and 4GB more VRAM, making it a better investment for 4K gaming and future-proofing. If you play at 1440p, the RTX 5070 provides good performance at a lower cost, so the value depends on your resolution and performance needs.

Can the RTX 5070 handle 4K gaming?

The RTX 5070 can handle 4K gaming in less demanding titles or with DLSS enabled, but its 12GB of memory and lower bandwidth may limit performance in the most demanding games. For a consistent 4K experience, the RTX 5080 is a better choice. Check our 4K gaming PCs guide for systems that pair well with these cards.

Do both cards support DLSS 5?

Yes, both the RTX 5070 and RTX 5080 support DLSS 5, including features like 3D-Guided Neural Rendering and Dynamic Multi Frame Generation. The Tensor Cores are the same generation, though the RTX 5080 has higher AI TOPS. Learn more about DLSS in our DLSS guide.

Which card is better for streaming?

Both cards have the ninth-generation NVENC encoder, but the RTX 5080 has two encoders, which can handle more simultaneous encoding tasks. For most streamers, the RTX 5070's single encoder is sufficient, but the RTX 5080 offers more headroom for 4K streaming or multi-platform broadcasts. See our streaming PCs guide for more.
