AX Gaming GeForce RTX 5090 D X3W VS Colorful iGame GeForce RTX 5070 Ti Ultra W OC

At first glance, the Colorful iGame RTX 5070 Ti Ultra W OC appears to have a clock speed advantage, running a base of 2295 MHz and a turbo of 2497 MHz compared to the AX Gaming RTX 5090 D X3W's 2017 MHz / 2407 MHz. However, clock speed alone is a misleading metric when comparing GPUs from different tiers — what truly matters is how many execution units those clocks are driving.

The RTX 5090 D X3W operates on an entirely different scale in terms of raw silicon. With 21,760 shading units, 680 TMUs, and 176 ROPs, it dwarfs the RTX 5070 Ti's 8,960 shaders, 280 TMUs, and 96 ROPs — roughly 2.4× more rendering resources across the board. This translates directly into the throughput numbers: the 5090 D delivers 104.8 TFLOPS of floating-point performance versus 44.75 TFLOPS for the 5070 Ti, and a texture rate of 1,637 GTexels/s against 699.2 GTexels/s. In practice, this means the 5090 D can push far more geometry, shading complexity, and compute workloads simultaneously — a decisive advantage in high-resolution gaming, AI-accelerated rendering, and compute tasks alike. Both cards share the same 1750 MHz memory speed and both support Double Precision Floating Point, so those factors do not differentiate them here.

The AX Gaming RTX 5090 D X3W holds a clear and commanding performance advantage in this group. The 5070 Ti's higher clock speeds cannot compensate for its significantly smaller shader array; the 5090 D's throughput leads of roughly 2.3× in TFLOPS and pixel rate make it the dominant card for demanding workloads. The 5070 Ti remains competitive in its own tier, but on pure performance metrics, there is no contest between these two.

Both cards share the same GDDR7 memory type and identical 28000 MHz effective memory speed, so the quality and frequency of the memory chips themselves are evenly matched. Where they diverge sharply is in how much of that memory is available and how wide the pipeline is to access it.

The RTX 5090 D X3W pairs a 512-bit memory bus with 32GB of VRAM, yielding a maximum bandwidth of 1790 GB/s — exactly double the 5070 Ti Ultra W OC's 256-bit bus, 16GB, and 896 GB/s. The bus width is the key lever here: it determines how many bits the GPU can move per clock cycle, and doubling it directly doubles peak throughput at the same memory speed. In practice, this bandwidth gap matters most at high resolutions and with texture-heavy workloads, where the GPU constantly needs to stream large amounts of data to and from VRAM. The 32GB capacity also gives the 5090 D a meaningful edge for scenarios that are increasingly VRAM-constrained — think 4K gaming with high-resolution texture packs, multi-display setups, or running large AI inference models locally. Both cards support ECC memory, which is a useful reliability feature for professional and compute workloads.

The AX Gaming RTX 5090 D X3W wins this category decisively, offering twice the VRAM capacity and twice the memory bandwidth thanks to its wider bus. For users operating at the bleeding edge of resolution or compute demands, that gap is not a marginal advantage — it is the difference between being constrained by memory and not.

Across every feature in this group, the AX Gaming RTX 5090 D X3W and the Colorful iGame RTX 5070 Ti Ultra W OC are in complete lockstep. Both run DirectX 12 Ultimate — the current gold standard for modern gaming APIs, enabling features like hardware-accelerated ray tracing, mesh shaders, and variable-rate shading. They share the same OpenGL 4.6 and OpenCL 3 support, keeping both cards well-covered for creative, scientific, and legacy workloads.

On the gaming feature side, both support ray tracing and DLSS, the latter being particularly significant as it uses AI-based upscaling to recover performance lost to demanding rendering techniques — a crucial tool at high resolutions. Both also support up to 4 simultaneous displays and include Intel Resizable BAR, which allows the CPU to access the full GPU frame buffer at once rather than in chunks, offering a modest but measurable performance uplift in supported titles. RGB lighting is present on both as well.

This group is a complete tie. There is no feature differentiator between these two cards — a buyer choosing between them based on software capabilities and API support will find nothing to separate them here. The decision must rest entirely on the performance and hardware specifications covered in other groups.

Port selection is identical on both cards: each offers 1 HDMI 2.1b output and 3 DisplayPort outputs, totaling 4 display connections — consistent with the 4-display limit noted in the Features group. HDMI 2.1b is the latest revision of the standard, supporting up to 10K resolution and high refresh rates at 4K and 8K, making it well-suited for high-end gaming monitors and modern TVs alike. The three DisplayPort outputs provide flexible multi-monitor configurations for productivity or immersive gaming setups.

Neither card includes USB-C, DVI, or mini DisplayPort outputs, so users with older monitors relying on DVI will need an adapter regardless of which card they choose. The absence of USB-C is worth noting for those who use USB-C-connected displays or VR headsets that rely on that interface directly from the GPU.

This is another complete tie — every port type, count, and version is identical across both cards. Connectivity will not factor into a purchase decision between these two products.

Both cards are built on the same Blackwell architecture, manufactured on a 5 nm process node, and connect via PCIe 5.0 — so the generational foundation is identical. The divergence lies in scale. The RTX 5090 D X3W packs 92,200 million transistors compared to the RTX 5070 Ti Ultra W OC's 45,600 million, reflecting roughly twice the die complexity. This aligns precisely with the 2× performance gap seen in compute and memory throughput across other spec groups — the silicon difference here is the root cause of everything else.

The most practically significant difference for system builders is power consumption. The RTX 5090 D X3W carries a 575W TDP versus the 5070 Ti's 300W — a gap of 275W that has real consequences. A system running the 5090 D will require a substantially more powerful PSU, likely 1000W or above when accounting for the rest of the platform, and will generate considerably more heat, placing higher demands on case airflow and ambient cooling. The 5070 Ti, at 300W, is far more manageable in a typical high-end gaming build. Neither card uses air-water hybrid cooling, so both rely entirely on their air cooler solutions to handle their respective thermal loads.

Physically, the 5090 D is also the larger card at 358 × 148 mm versus 331 × 139.3 mm for the 5070 Ti, so case clearance should be verified for the 5090 D in particular. On this group, there is no single winner — the 5070 Ti has a clear advantage in power efficiency and build compatibility, while the 5090 D's transistor count underpins its dominant performance figures. The right choice depends entirely on whether a buyer's system and environment can accommodate the 5090 D's substantially higher demands.
