Performance and where it ranks
Two different questions, side by side. Performance compares what the hardware can do; Value compares what that capability costs at today’s price. A product can rank high on one and low on the other — that gap is the point.

Balanced has no letter: it is a weighting preset, not a capability rubric. A grade answers “how well does this handle that job?” — price is never part of it. Relative Value puts the current market price back in.

For the selected scenario this is not a strong fit — the grade above is the reason, and the models below suit it better.

- Light Use is not actually your main job — 1080p Gaming isit grades D for Light Use, but S for 1080p Gaming
Consider other options if
- Not the pick if Light Use is your main useit grades D there; RTX 3050 6GB grades S at CAD 600
- You want strong value for Light Use specificallycompeting products deliver so much more for Light Use per dollar that no price this model realistically trades at reaches the strong-value mark for this job
- Value for money matters more to you than this exact modelGTX 1650 holds Relative Value 100 against its 1 for Light Use, at CAD 210

Chosen for AI
This scenario carries a requirement candidates are checked against first: CUDA — Many local-LLM and diffusion toolchains are CUDA-only. ROCm and Vulkan builds exist and work, but they are not drop-in — check your toolchain before treating a non-NVIDIA card as an equivalent swap.
Chosen for 3D Rendering
This scenario carries a requirement candidates are checked against first: OptiX — Blender Cycles reaches its fastest path on NVIDIA OptiX. HIP (AMD) and oneAPI (Intel) render the same scenes, so this is a workflow question, not a capability wall — but render times and add-on support differ.
Chosen for Light Use
Alternatives stay near this product’s price range. Step-up options may exceed the standard budget envelope when the capability gain is meaningful.

Judge the change in the active scenario, then make the cash gap explicit.
Using page scenarioWhat are you upgrading from? These are the axes we compare on, and where this product stands in the current market.
We rank upgrades by out-of-pocket cost — the new price minus what yours is worth — not by sticker price.
Only candidates that clear the configured meaningful-upgrade gate will be shown; roles are omitted rather than filled.
Capability differences are expressed as tiers and index points, not as benchmark percentages we did not measure.

850 W PSU recommended
Whole-system figure from the board vendor — it already allows for the processor and transient spikes.
1x 16-pin required
Adapters work but add connector bulk and need extra cable-bend clearance.
Needs at least 358 mm of GPU clearance
Front radiators and fans eat into the figure a case advertises.
Leave room beyond the card for the cable bend
No verified minimum is published — measure it.
Occupies 4 slots
The cooler covers the slots below it — check nothing adjacent needs that space.

FAQ
Do all RTX 4090 boards have the same physical design?
No. Dimensions, slot thickness, cooling, power connectors and display outputs belong to the exact board. Use the Exact version selector before checking case or PSU fit.
How much case clearance should I allow for the RTX 4090?
Tracked boards range from 331 to 358 mm in length. Select the exact board, then also allow for front radiators or fans, card height, slot thickness and power-cable bend; length alone does not guarantee fit.
Why does Relative Value change when I choose another scenario?
Each scenario changes the weights applied to capability, price and the other published factors. The hardware facts stay fixed, but the value question changes, so its score and rank can change too.
Why can Amazon appear without a tracked price?
Amazon listing snapshots can participate in Value while fresh. We show Check on Amazon instead of its price; confirm the current price and availability at the store. When no current listing snapshot exists, Amazon is a search link only.
