Understanding GPU specifications

CUDA cores vs stream processors

CUDA cores (NVIDIA): These are parallel processing units that handle multiple tasks simultaneously. More CUDA cores generally mean better performance for gaming, 3D rendering, and compute tasks. NVIDIA’s RTX 50-series uses the Blackwell architecture, with improved cores and dedicated hardware for DLSS 4.

Stream processors (AMD): AMD’s equivalent to CUDA cores. While you can’t directly compare core counts between manufacturers due to different architectures, AMD’s RDNA 4 architecture (RX 9000 series) delivers excellent performance per Stream Processor and much-improved ray tracing over RDNA 3.

Memory types: GDDR6 vs GDDR6X vs GDDR7

GDDR6: Standard video memory used in most recent mid-range GPUs and across AMD’s RX 7000 and RX 9000 lineups. Offers excellent bandwidth for 1080p and 1440p gaming.

GDDR6X: NVIDIA’s faster memory used on higher-end RTX 30 and RTX 40-series cards, providing more bandwidth for 4K gaming and professional workloads.

GDDR7: The newest standard, used across NVIDIA’s RTX 50-series (Blackwell). It offers a significant bandwidth jump over GDDR6X, which helps most at 4K and in memory-heavy creative and AI workloads.

Memory size requirements

  • 8GB: Workable for 1080p gaming at high settings, though some new titles are starting to push past it
  • 12GB: A comfortable minimum for 1440p gaming today
  • 16GB: The sweet spot for 1440p/4K gaming, video editing, and 3D rendering
  • 24-32GB: Professional workloads, AI/ML tasks, and no-compromise 4K (e.g. RTX 5090 with 32GB)

Clock speeds explained

Base clock: The guaranteed minimum frequency your GPU will run at under load. This is the conservative speed that ensures stability.

Boost clock: The maximum frequency your GPU can reach under optimal conditions. Modern GPUs dynamically boost based on temperature and power availability. Real-world boost clocks often exceed the rated spec.

TDP (thermal design power)

TDP indicates how much power your GPU consumes and how much heat it generates. This is crucial for choosing the right power supply and cooling solution:

  • 75W or less: Entry-level cards that don’t require external power connectors
  • 150-220W: Mid-range cards (e.g. RTX 5060 Ti, RX 9060 XT) requiring one or two PCIe power connectors
  • 250-320W: High-end cards (e.g. RTX 5070 Ti, RX 9070 XT) needing two 8-pin connectors or a 12V-2×6 cable
  • 360-575W: Flagship cards (RTX 5080 at 360W, RTX 5090 at 575W) requiring a 12V-2×6 power connector

Ray tracing technology

Ray tracing simulates realistic lighting, shadows, and reflections in real-time. Both NVIDIA and AMD offer hardware-accelerated ray tracing, and AMD has closed much of the gap with RDNA 4:

  • NVIDIA: 3rd Gen RT cores (RTX 40-series), 4th Gen RT cores (RTX 50-series / Blackwell)
  • AMD: RDNA 2 Ray Accelerators (RX 6000), enhanced RDNA 3 (RX 7000), much-improved RDNA 4 (RX 9000)

Upscaling: DLSS vs FSR

Upscaling renders a game at a lower resolution and intelligently reconstructs it, boosting frame rates with minimal quality loss:

  • NVIDIA DLSS 4: AI-based upscaling with Multi-Frame Generation on RTX 50-series, the current image-quality leader
  • AMD FSR 4: AMD’s new AI-based upscaler on RDNA 4, a big step up that closes most of the gap with DLSS

PCIe interface

Modern GPUs use PCIe 4.0 or 5.0 interfaces. The RTX 40-series and RX 7000 series use PCIe 4.0, while the current RTX 50-series (Blackwell) and RX 9000 series (RDNA 4) move to PCIe 5.0. PCIe 5.0 cards are backwards-compatible with PCIe 4.0 slots, with negligible real-world impact on current cards.

Frequently asked questions

How do I compare GPUs on Techsavant?

To compare graphics cards, simply check the boxes next to 2-3 GPUs you’re interested in from the database above. Once selected, click the “Compare” button that appears. You’ll see a side-by-side comparison showing CUDA cores/Stream Processors, memory specifications, TDP, clock speeds, and all other key specifications to help you make an informed decision.

Which GPU is best for gaming?

The best GPU depends on your resolution and budget. For 1080p, the Intel Arc B580 and RTX 5060 offer excellent value. For 1440p, the AMD RX 9070 XT is the standout value card, with the RTX 5070 Ti the pick if you want ray tracing and DLSS 4 fully enabled. For 4K, the RTX 5080 is the practical choice for most people, while the RTX 5090 delivers uncompromised native 4K and path tracing at the top end.

What’s the difference between NVIDIA and AMD GPUs?

NVIDIA GPUs typically lead in ray tracing performance and offer DLSS 4 with Multi-Frame Generation for AI-upscaling. They also have stronger support for professional applications and CUDA acceleration. AMD GPUs often provide better value for pure rasterization performance and come with more VRAM at similar price points. AMD’s FSR 4 is now AI-based and has closed most of the image-quality gap with DLSS.

How much VRAM do I need for gaming?

For 1080p gaming, 8GB VRAM works for most games at high settings, though a few of the newest titles are starting to push past it. For 1440p, aim for 12-16GB to ensure smooth performance in demanding titles. For 4K gaming or future-proofing, 16GB or more is recommended. Content creators and professionals should consider 16GB+ for video editing, 3D rendering, and AI workloads.

What PSU wattage do I need for my GPU?

Calculate your PSU needs based on your GPU’s TDP plus your CPU and other components. As a general guide: mid-range GPUs (around 200W) suit a 650-750W PSU, high-end cards like the RX 9070 XT or RTX 5070 Ti (around 300W) want 750-850W, the RTX 5080 (360W) is comfortable on 850W, and the RTX 5090 (575W) needs a 1000W+ unit with a native 12V-2×6 connector. Always choose a quality 80+ Gold or Platinum rated power supply — and you can size it with our PSU calculator.

Should I buy NVIDIA or AMD?

Choose NVIDIA if you prioritize ray tracing, DLSS 4, CUDA for professional work, or want the absolute best performance regardless of price. Choose AMD if you want better value, more VRAM at similar price points, or prefer the strong raster performance and improved FSR 4 of the RX 9000 series. Both manufacturers offer excellent gaming performance — your choice often comes down to specific features and budget. Intel’s Arc B-series is also now a genuine budget option worth considering.

How often are new GPUs released?

Major GPU generations are typically released every 2 years. NVIDIA launched the RTX 40-series in 2022-2024 and the current RTX 50-series (Blackwell) in early 2025. AMD launched the RX 7000 series in 2022-2023 and the current RX 9000 series (RDNA 4) in 2025. Intel’s Arc Battlemage (B-series) also arrived in this cycle. Between major releases, manufacturers often introduce “Super,” “XT,” or “Ti” variants with improved specs. We update our database regularly with all new releases.

💡 Pro Tip

Use our comparison tool to check not just gaming performance specs, but also memory bandwidth, process node, and TDP. A GPU might have more cores but higher power consumption – factor in electricity costs and cooling requirements when making your decision.
