Colorful iGame GeForce RTX 5080 Advanced OC VS Inno3D GeForce RTX 5080 X3 Gaming OC

Both the Colorful iGame Advanced OC and the Inno3D X3 Gaming OC are built on the same GPU silicon, and it shows: they share an identical base clock of 2295 MHz, the same 10752 shading units, 336 TMUs, 112 ROPs, and a 1875 MHz memory speed. This means the vast majority of their compute architecture is functionally equivalent out of the box.

The only meaningful differentiator within this spec group is the GPU boost clock. The Inno3D X3 Gaming OC reaches 2700 MHz versus the iGame Advanced OC's 2670 MHz — a 30 MHz advantage that flows directly into every derived metric: the X3 Gaming OC edges ahead with 58.06 TFLOPS of floating-point throughput versus 57.42 TFLOPS, a texture rate of 907.2 GTexels/s versus 897.1, and a pixel rate of 302.4 GPixel/s versus 299. In practice, a ~1.1% boost clock difference is unlikely to produce a perceptible framerate gap in most workloads, but it does represent a real, consistent lead for the Inno3D card.

The edge in this group goes to the Inno3D GeForce RTX 5080 X3 Gaming OC. While the advantage is slim, it is uniform across all performance-derived specs, meaning the Inno3D card is the faster binned or tuned variant of the two. For users comparing these cards purely on GPU throughput, the X3 Gaming OC is the stronger choice — if only by a narrow margin.

On memory, these two cards are carbon copies of each other. Both feature 16GB of GDDR7 running across a 256-bit bus at an effective speed of 30000 MHz, delivering 960 GB/s of peak bandwidth. That bandwidth figure is particularly significant: it places both cards well above previous-generation flagships, and in bandwidth-hungry workloads — think high-resolution texturing, large asset streaming, or AI inference — this headroom translates directly into smoother, more sustained throughput.

The 256-bit bus width paired with GDDR7 is worth noting as an architectural choice. Rather than widening the bus further, GDDR7's higher per-pin efficiency achieves competitive bandwidth at a narrower width, which generally favors power efficiency and die area. Both cards benefit equally from this design. ECC memory support is also present on both, which is a useful reliability feature for users running compute or professional workloads alongside gaming.

This group is a complete tie. There is no differentiator anywhere in the memory spec set — every figure is identical. A buyer's decision between the iGame Advanced OC and the X3 Gaming OC cannot be informed by memory alone, and neither card holds any advantage here.

Feature parity is total between these two cards. Both support DirectX 12 Ultimate — the current gold standard for gaming APIs, enabling hardware-accelerated ray tracing, mesh shaders, and variable rate shading across compatible titles. Alongside this, DLSS support is present on both, which is arguably the most practically impactful feature for end users: DLSS's AI-driven upscaling allows games to render at lower resolutions and reconstruct sharp, high-fidelity frames, significantly boosting performance at 4K and beyond with minimal visual compromise.

Ray tracing support and up to 4 simultaneous displays round out the shared feature set meaningfully. Multi-display capability at this level suits both enthusiast gaming setups and productivity-heavy workstations. The inclusion of Intel Resizable BAR on both cards also ensures the CPU can access the full GPU framebuffer at once, a low-level optimization that can yield measurable framerate improvements in supported games without any user configuration.

As with the memory group, this is an exact tie. Every feature flag — from RGB lighting to the absence of LHR — is identical across both cards. No advantage can be drawn here, and prospective buyers should look to other spec groups, such as performance or connectivity, to differentiate the two.

Connectivity is identical across both cards. Each offers the same layout: three DisplayPort outputs and one HDMI 2.1b port, totaling four display outputs — consistent with the four-display maximum noted in the features group. For most users, three DisplayPorts alone is sufficient to drive a triple-monitor gaming or productivity setup, while the HDMI port handles a TV, projector, or any display that lacks a DisplayPort input.

The HDMI 2.1b version is worth calling out. It supports bandwidth sufficient for 4K at very high refresh rates and 8K output, making both cards well-suited for next-generation display technology without requiring adapters or workarounds. The absence of USB-C on both cards is notable for users who prefer that connector for modern monitors, though this affects neither card disproportionately since both are in the same position.

This group is another complete tie. Port configuration is a pixel-perfect match between the iGame Advanced OC and the X3 Gaming OC, and no advantage exists for either card in terms of display connectivity.

Under the hood, both cards share the same Blackwell architecture built on a 5nm process with 45.6 billion transistors, confirming they are variants of the same silicon. PCIe 5 support on both ensures neither card is bottlenecked by the interface on any modern platform. Where things diverge, however, is in power draw and physical footprint — and the gaps are significant enough to influence a buying decision.

The Colorful iGame Advanced OC carries a TDP of 390W, versus 360W for the Inno3D X3 Gaming OC — a 30W difference. This matters in two practical ways: first, PSU headroom requirements are higher for the iGame, meaning users with tighter power budgets need to account for this; second, a higher TDP in a card with only marginally higher boost clocks (as seen in the performance group) suggests the iGame runs less efficiently per watt. The X3 Gaming OC actually achieves comparable or slightly higher peak clocks while drawing less power, which is a meaningful efficiency advantage. Physical size tells a similar story: the iGame measures 355 × 144.7 mm while the X3 Gaming OC is notably more compact at 300 × 120 mm. That 55mm length difference is substantial — smaller cases that cannot accommodate a 355mm card will be locked out of the iGame entirely.

The edge in this group goes clearly to the Inno3D X3 Gaming OC. It runs cooler on paper, draws less power, and fits into a wider range of chassis — all without sacrificing meaningful performance. For builders working with smaller cases or efficiency-conscious builds, the X3 Gaming OC is the more practical choice by a considerable margin.
