Hardware buying comparisons
Compare GPUs across brands and generations
Start with the job you need the hardware to do. These 18 comparisons cover memory, software compatibility and dated asking-price samples. Similar models are shopping alternatives; they are not guaranteed performance equivalents.
NVIDIA vs AMD
RTX 3060 12GB vs RX 6700 XT: which should you buy?
A used-budget NVIDIA/AMD comparison with 12GB on each card. Matching memory makes this a useful shortlist, but does not imply matching gaming or AI performance.
RTX 5070 Ti vs RX 9070 XT: 16GB alternatives for gaming and local AI
Two 16GB cards to shortlist for a new gaming or local-AI build. This is a buying comparison, not a claim of identical frame rates.
RTX 5070 vs RX 9070: 12GB or 16GB for your next build?
A current-generation NVIDIA/AMD shortlist where the main specification difference is 12GB versus 16GB. Similar shopping intent does not mean equal performance.
RTX 5060 Ti 16GB vs RX 9060 XT 16GB: compare the exact 16GB versions
Two 16GB options for buyers who want memory capacity without moving to a higher card tier. Both families also have 8GB variants, which are not the products compared here.
RTX 4070 Super vs RX 7800 XT: used value, 12GB vs 16GB and software
A previous-generation NVIDIA/AMD shortlist for used buyers, with 12GB on the GeForce and 16GB on the Radeon.
RTX 4070 Ti Super vs RX 7900 XT: 16GB CUDA or 20GB Radeon?
A higher-memory used-card shortlist: the RTX 4070 Ti Super provides 16GB and the RX 7900 XT provides 20GB.
RTX 4080 Super vs RX 7900 XTX: 16GB vs 24GB for gaming and local AI
High-end alternatives with different memory ceilings: 16GB on the RTX 4080 Super and 24GB on the RX 7900 XTX.
RTX 3080 10GB vs RX 6800 XT: older used GPUs, memory and compatibility
Two older used-market alternatives. This page deliberately compares the original 10GB RTX 3080 with the 16GB RX 6800 XT; the 12GB RTX 3080 is a separate configuration.
RTX 3090 vs RX 7900 XTX: 24GB CUDA vs 24GB ROCm
Compare RTX 3090 vs RX 7900 XTX by memory, supported software, current asking-price samples and total purchase cost.
NVIDIA upgrades and Mac alternatives
RTX 5070 Ti vs RTX 4070 Ti Super: which should you buy?
A generation-upgrade decision between two 16GB NVIDIA cards. Compare the cost of keeping your existing card with replacing it, not just the two asking prices.
RTX 3090 vs RTX A6000: which should you buy?
A 24GB consumer card versus a 48GB workstation card for local AI. The RTX A6000 is the Ampere model, not the RTX 6000 Ada or RTX PRO 6000 Blackwell.
RTX 5060 Ti 16GB vs RTX 4060 Ti 16GB: which should you buy?
Two generations of 16GB GeForce cards for buyers prioritizing model capacity. Both families also have 8GB versions; those listings are not equivalent to the configurations here.
RTX 3090 vs RTX 4090: which used card for local AI?
Compare RTX 3090 vs RTX 4090 by memory, supported software, current asking-price samples and total purchase cost.
Mac Studio vs RTX 4090: which local AI box?
Compare Mac Studio vs RTX 4090 by memory, supported software, current asking-price samples and total purchase cost.
RTX 4090 vs RTX 5090 for LLMs: is the upgrade worth it?
A 24GB-to-32GB upgrade decision for local LLM inference. Compare memory fit, measured performance and the amount you would actually spend to replace a working 4090.
RTX 3080 vs RTX 4070: cheap veteran or efficient successor?
Compare RTX 3080 vs RTX 4070 by memory, supported software, current asking-price samples and total purchase cost.
RTX 4080 vs RTX 4090: 16GB value or 24GB ceiling?
Compare RTX 4080 vs RTX 4090 by memory, supported software, current asking-price samples and total purchase cost.
RTX 5070 vs RTX 4070 Super: which 12GB card to buy used?
Compare RTX 5070 vs RTX 4070 Super by memory, supported software, current asking-price samples and total purchase cost.
