RTX 4090 vs SiS Mirage: which should you choose?
RTX 4090 — NVIDIA desktop graphics card (2022, Ada Lovelace) with 24 GB of GDDR6X, averaging 153 fps at 1440p; launched at $1,599.
SiS Mirage — SiS integrated graphics processor (2000, SiS 2nd Gen) with 66 MB of Shared.
RTX 4090 vs SiS Mirage: a cross-generation spec comparison. These GPUs come from different eras (2022 vs 2000), 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 4090 (2022, Desktop) and SiS Mirage (2000, Integrated) 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 4090 carries 24 GB of GDDR6X against 66 MB of Shared on SiS Mirage, with board powers of 450 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
Is the RTX 4090 better than the SiS Mirage?
RTX 4090 takes the overall edge, though SiS Mirage wins in specific areas worth weighing. These GPUs come from different eras (2022 vs 2000), so direct benchmark comparisons are not meaningful. The table shows their specifications side by side for historical and architectural context.

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.
