Gainward GeForce RTX 5070 Ti Phoenix-S VS MSI GeForce RTX 5070 Ti Shadow 3X OC

At the foundation, both the Gainward Phoenix-S and the MSI Shadow 3X OC are built on identical silicon configurations: 8960 shading units, 280 TMUs, and 96 ROPs — meaning neither card has a hardware advantage in terms of raw compute resources. Memory is also clocked identically at 1750 MHz on both. The real differentiator lives entirely in the boost clock: the MSI Shadow 3X OC is factory-tuned to a 2482 MHz turbo, versus 2452 MHz on the Gainward Phoenix-S — a 30 MHz edge that, while modest in percentage terms (~1.2%), directly lifts every performance metric derived from it.

That clock advantage cascades into a small but consistent lead for the MSI across throughput figures: 44.48 TFLOPS of floating-point performance versus 43.94 TFLOPS, and a texture fill rate of 695 GTexels/s compared to 686.6 GTexels/s. In practice, these differences are unlikely to be perceptible in standard gaming workloads, but they can matter at the margins in heavily shader-bound or compute-intensive scenarios. Both cards support Double Precision Floating Point, which is relevant for mixed-precision compute tasks beyond gaming.

The MSI Shadow 3X OC holds a narrow but clear performance edge in this group, courtesy of its higher factory boost clock translating into slightly better throughput across all derived metrics. The Gainward Phoenix-S is not meaningfully behind — the gap is small enough that real-world gaming frame rates would rarely diverge — but on paper, the MSI is the faster card of the two.

Memory is a complete dead heat between these two cards. Both carry 16GB of GDDR7 across a 256-bit bus, running at an effective 28000 MHz for a peak bandwidth of 896 GB/s. GDDR7 is the latest generation of graphics memory, delivering substantially higher efficiency and throughput per pin compared to GDDR6X — so both cards benefit equally from that architectural uplift.

The 896 GB/s bandwidth figure is particularly significant in practice: it means neither card will be memory-starved in high-resolution, texture-heavy workloads or when running large generative AI models locally. The 16GB frame buffer is also a comfortable ceiling for 4K gaming with high-resolution texture packs and for professional creative tasks that push VRAM limits. ECC memory support on both cards adds a layer of data integrity relevant to compute and workstation use cases, though it has no impact on gaming performance.

This group is an absolute tie. Every memory specification — capacity, type, speed, bus width, and ECC support — is shared identically between the Gainward Phoenix-S and the MSI Shadow 3X OC. Buyers looking to differentiate between these two cards will need to look elsewhere.

From a software and API standpoint, these two cards are functionally identical. Both support DirectX 12 Ultimate, ray tracing, and DLSS — the trio that defines the modern high-end gaming feature set. DirectX 12 Ultimate in particular ensures compatibility with the full range of next-generation rendering features including hardware-accelerated ray tracing and variable rate shading. Neither card supports XeSS, which is expected given that is an Intel-native upscaling technology. Both also support Intel Resizable BAR, which allows the CPU to access the full GPU frame buffer simultaneously, offering measurable performance gains in supported titles.

The one concrete differentiator in this group is RGB lighting: the Gainward Phoenix-S includes it, while the MSI Shadow 3X OC does not. For users building aesthetically themed systems, this distinction is meaningful — RGB on the Gainward allows synchronization with other components in a lighting ecosystem, whereas the MSI takes a purely utilitarian visual approach. Neither choice affects gaming or compute performance in any way.

For feature parity, these cards are essentially tied — but the Gainward Phoenix-S claims a minor edge for buyers who value RGB integration. If aesthetics are irrelevant to the purchase decision, this group offers no basis for choosing one card over the other.

Connectivity is identical across both cards. Each offers 3 DisplayPort outputs and 1 HDMI 2.1b port, totaling four display outputs — matching the supported display count listed in the features specifications. The absence of USB-C, DVI, and mini DisplayPort is consistent with modern high-end GPU design, where those legacy or niche connectors have been phased out in favor of the current standard interfaces.

HDMI 2.1b is the most capable version of HDMI currently available, supporting up to 4K at very high refresh rates and 8K output — relevant for users connecting to high-end TVs or next-generation monitors. The three DisplayPort outputs, meanwhile, provide ample flexibility for multi-monitor workstation setups or gaming rigs. Together, the four-port configuration means neither card will bottleneck a demanding multi-display arrangement.

This group is a straightforward tie. The Gainward Phoenix-S and MSI Shadow 3X OC offer an identical port layout in every respect, giving buyers no connectivity-based reason to favor one over the other.

Sharing the same Blackwell architecture, 5nm process node, and a transistor count of 45.6 billion, these two cards are cut from exactly the same silicon cloth. The identical 300W TDP and PCIe 5.0 interface mean power delivery requirements and motherboard compatibility are the same across both — buyers will need the same PSU headroom and connector setup regardless of which card they choose.

Where this group surfaces a real distinction is in physical dimensions. The MSI Shadow 3X OC measures 303 mm × 121 mm, while the Gainward Phoenix-S is notably larger at 331.9 mm × 127.1 mm — nearly 29mm longer and 6mm taller. That difference is practically significant: in smaller mid-tower or compact ATX cases, the MSI is the more accommodating card. Users should measure their case clearance before committing, as the Gainward's length could be a hard constraint in tighter builds.

For general specifications, both cards are equal in every performance-relevant dimension. The MSI Shadow 3X OC earns a practical edge here solely on the basis of its more compact footprint, making it the more case-friendly option for builders working with limited interior space.
