RTX 5090 vs SiS 6326: a cross-generation spec comparison. These GPUs come from different eras (2025 vs 1997), so direct benchmark comparisons are not meaningful. The table shows their specifications side by side for historical and architectural context.
Different eras, different missions
These two parts do not compete head-to-head: RTX 5090 (2025, Desktop) and SiS 6326 (1997, Desktop) come from different generations or market segments, so modern game benchmarks do not apply to both. The specification table above is best read as architectural context — process node, memory technology and power budgets show how far GPU design has moved.
Specifications at a glance
RTX 5090 carries 32 GB of GDDR7 against 4 MB of EDO on SiS 6326, with board powers of 575 W and 5 W respectively.
The verdict
Both are credible choices in the graphics card comparison space; the specification table above lays out every metric so you can weigh the trade-offs that matter to you. Pick the one whose strengths line up with how you will actually use it.
Frequently asked questions

Methodology
Graphics cards are compared on 3DMark Time Spy scores, average gaming frame rates at 1080p/1440p/4K, FP32 compute throughput, VRAM capacity and type, memory bandwidth, board power (TDP) and launch MSRP — plus AI workload throughput (Stable Diffusion iterations/s and local LLM tokens/s) where measured. Vintage and server GPUs without modern benchmark results are compared on specifications only, clearly labelled. Frame rates are averages across a game suite at high settings; specific titles vary.
