Colorful GeForce RTX 5070 Ti NB EX VS Manli Stellar GeForce RTX 5070 Ti OC

At the core, both the Colorful NB EX and the Manli Stellar OC are built on identical GPU silicon: the same 8960 shading units, 280 TMUs, and 96 ROPs, with a matching base clock of 2295 MHz and memory speed of 1750 MHz. This means their theoretical throughput ceiling is defined almost entirely by how aggressively each card boosts under load.

That is precisely where the two diverge. The Manli Stellar OC reaches a higher GPU turbo of 2482 MHz versus the Colorful NB EX's 2452 MHz — a 30 MHz, or roughly 1.2%, advantage. While that gap sounds slim, it cascades across every derived metric: the Manli edges ahead in floating-point performance (44.48 vs 43.94 TFLOPS), texture fill rate (695 vs 686.6 GTexels/s), and pixel rate (238.3 vs 235.4 GPixel/s). In practice, this translates to a marginally faster card in sustained GPU-bound workloads, though the real-world frame rate difference will typically fall within the noise floor of most gaming benchmarks.

Overall, the Manli Stellar OC holds a narrow but consistent performance edge in this group, courtesy of its higher factory boost clock. Both cards support Double Precision Floating Point, making them equally capable for compute tasks that leverage DPFP. For users prioritizing peak GPU throughput out of the box, the Manli has the measurable — if modest — advantage.

Memory is one area where choosing between these two cards becomes straightforward: every single specification is identical. Both feature 16GB of GDDR7 VRAM running at an effective 28000 MHz across a 256-bit bus, delivering a peak bandwidth of 896 GB/s. That bandwidth figure is substantial — it ensures the GPU can feed its shader units efficiently even at 4K resolutions or in memory-intensive workloads like generative AI inference and large texture streaming.

GDDR7 represents a meaningful generational leap over GDDR6X, and 16GB remains a comfortable buffer for current and near-future AAA titles, content creation workflows, and local AI tasks. The shared support for ECC memory is a welcome addition for users running professional or compute workloads where data integrity matters, though it has no bearing on gaming performance.

This group is a complete tie. There is no memory-related reason to prefer one card over the other — buyers can set this spec group aside entirely and focus their decision on the differences identified elsewhere.

The feature sets of these two cards are nearly identical across the board — both support DirectX 12 Ultimate, ray tracing, DLSS, OpenCL 3, and Intel Resizable BAR, and both can drive up to 4 displays simultaneously. For the vast majority of users, this shared foundation means equivalent compatibility with modern games, rendering APIs, and GPU-accelerated software.

The one concrete differentiator here is 3D support: the Colorful NB EX lists it as supported, while the Manli Stellar OC does not. In practical terms, 3D output — used for stereoscopic display technologies — is a niche capability with a narrow audience today. For anyone specifically invested in stereoscopic 3D setups, this distinction matters; for everyone else, it is unlikely to influence a purchase decision.

On balance, the Colorful NB EX holds a technical edge in this group solely due to its 3D support. That said, the advantage is highly situational — if stereoscopic 3D is not part of your workflow or entertainment setup, the two cards are effectively feature-equivalent.

Connectivity is another area where these two cards are in complete lockstep. Both offer the same output configuration: 3 DisplayPort outputs and 1 HDMI 2.1b port, totaling four display connections — which aligns with their shared 4-display support noted in the features group. The absence of USB-C, DVI, or mini DisplayPort outputs is equally consistent across both cards.

HDMI 2.1b is the key headline here, as it supports up to 10K resolution and high refresh rates at 4K and 8K — relevant for users with high-end TVs or next-generation monitors. The three DisplayPort outputs further accommodate demanding multi-monitor setups or high-refresh-rate gaming displays, providing ample flexibility for most desktop configurations.

This is an unambiguous tie. The port layout is byte-for-byte identical, so display connectivity should play no role whatsoever in choosing between the Colorful NB EX and the Manli Stellar OC.

Underneath, these two cards are built on the same foundation: the Blackwell architecture, a 5 nm process node, 45.6 billion transistors, a 300W TDP, and PCIe 5.0. That shared silicon and power envelope means identical platform requirements — same power connectors, same CPU bandwidth ceiling, same thermal load imposed on the system.

Where they diverge is physical footprint. The Colorful NB EX is the larger card at 330.6 × 140 mm, while the Manli Stellar OC measures a notably more compact 315 × 127 mm — roughly 15 mm shorter in length and 13 mm slimmer in height. That difference is meaningful in practice: the Manli is more likely to fit in smaller mid-tower or compact ATX cases where clearance around the GPU is tight, and it leaves more room for airflow or adjacent components.

For users building in spacious full-tower cases, the size gap is irrelevant. But in constrained builds, the Manli Stellar OC has a clear advantage here — its smaller footprint offers meaningfully better case compatibility without any trade-off in TDP or platform requirements.
