NVIDIA GeForce RTX 3080 12 GB

NVIDIA GeForce RTX 3080 12 GB is an Ampere-architecture part built on Samsung's 8 nm process, featuring a GA102 chip with 28,300 million transistors on a 628 mm² die. It is a dual-slot card with a 350 W TDP, requiring a 750 W suggested PSU and a single 12-pin power connector. The card is end-of-life, released on January 10, 2022, with a successor in the GeForce 40 series.

Memory Subsystem

The RTX 3080 12 GB is equipped with 12 GB of GDDR6X memory across a 384-bit bus, yielding a peak bandwidth of 912.4 GB/s. Memory clock runs at 1188 MHz, translating to 19 Gbps effective. This configuration gives the card a substantial memory throughput advantage for high-resolution workloads, particularly at 4K where texture data and geometry demands scale aggressively. The 384-bit bus width is a key enabler, as it allows the memory controller to feed the 8960 shading units and 280 texture mapping units without starvation. Compared to narrower-bus designs, this bandwidth headroom reduces the likelihood of frame-time hitches in scenes with heavy streaming, such as open-world titles with high-detail foliage or complex shadows. The 12 GB capacity, while not the largest on the market, is sufficient for current-generation titles at maximum settings in 4K, where allocations often approach 10-11 GB in the most demanding scenarios. For users targeting 1440p ultra-wide or 4K with high-resolution texture packs, the combination of capacity and 912.4 GB/s bandwidth ensures that memory is rarely the limiting factor; the pixel rate of 164.2 GPixel/s and texture rate of 478.8 GTexel/s further complement this, allowing the card to sustain high fill rates even with memory-intensive effects like depth of field and motion blur enabled.

Who Should Consider It

Benchmark data positions this card in the 26th percentile of all GPUs, which indicates it outperforms roughly three-quarters of the field in aggregate scoring. This makes it a strong candidate for gamers running at 1440p with high refresh rate displays, where the 30.64 TFLOPS FP32 throughput can drive frame rates well beyond 100 FPS in most esports and competitive titles. At 4K, the card remains viable for 60 FPS gaming in many AAA releases, but users should be prepared to adjust settings from "ultra" to "high" in the most demanding scenes to maintain consistent performance, particularly with ray tracing enabled. The 12 GB VRAM buffer is well-suited for 4K texture quality, and the bandwidth ensures that streaming assets do not cause stutter. For content creators, the 280 tensor cores provide acceleration for AI-assisted workflows, such as denoising and upscaling, though the 70 RT cores are the more relevant feature for real-time rendering tasks. This card is not intended for budget-oriented builds or low-resolution esports at 1080p, where its capabilities would be underutilized; it is a high-end part for users who prioritize resolution and visual fidelity over raw cost efficiency. The availability of DisplayPort 1.4a and HDMI 2.1 outputs also makes it suitable for connecting to 4K 120 Hz displays or 8K TVs, provided the rest of the system can keep pace.

Benchmark Performance

In the 3DMark Steel Nomad DX12 test, the RTX 3080 12 GB scores 4791 points. This result is identical to the Intel HD Graphics 530, which also averages 4791 points, showing a 0% delta. That is a surprising parity on paper, but the integrated Intel solution is not in the same performance class for real-world gaming; the synthetic test likely does not fully stress the discrete card's memory bandwidth or shader throughput. Against the NVIDIA GeForce GTX 560M, the RTX 3080 12 GB leads by 0.5%, as the GTX 560M scores 4769 points. This is a negligible margin, indicating that the older mobile GPU can match the new desktop card in this specific benchmark, which may reflect the test's limited reliance on VRAM or compute-heavy operations. The Intel HD Graphics P530 scores 4831 points, meaning the RTX 3080 12 GB trails by 0.8% — again a minor difference that suggests the benchmark is not differentiating between these vastly different hardware architectures. The AMD Radeon R6 M255DX posts 4867 points, putting the RTX 3080 12 GB 1.6% behind. These deltas are all within a 2% band, which is unusual for a card with 912.4 GB/s of bandwidth and 30.64 TFLOPS of compute; the data indicates that the 3DMark Steel Nomad test does not scale with the RTX 3080's strengths, possibly due to driver overhead or the test's particular workload mix. Nevertheless, the absolute score of 4791 places the card in the 26th percentile, so while its rival comparisons show near-parity, its overall standing in the full GPU distribution is above average, reinforcing that the synthetic test alone underestimates its real-world capabilities.

How It Compares

Against the Intel HD Graphics 530, the RTX 3080 12 GB shows no performance delta, with both scoring exactly 4791. This is a case where the benchmark result fails to reflect the architectural gulf — the integrated HD 530 lacks dedicated VRAM, has far lower memory bandwidth, and cannot sustain high resolutions, yet the Steel Nomad test records a tie. The RTX 3080's 12 GB GDDR6X and 384-bit bus are simply not exercised in a way that creates separation.

Versus the NVIDIA GeForce GTX 560M, the RTX 3080 12 GB is 0.5% ahead (4791 vs. 4769). The GTX 560M is a legacy mobile part from a previous generation, so this near-tie is more indicative of the benchmark's insensitivity to modern GPU features like tensor cores or ray tracing than of actual equivalence. In gaming workloads, the RTX 3080 would be orders of magnitude faster.

The Intel HD Graphics P530 scores 4831, meaning the RTX 3080 12 GB is 0.8% behind. Again, the P530 is an integrated solution with shared system memory, so this result is anomalous for a discrete card with dedicated GDDR6X. The data suggests that the 3DMark test does not penalize the lack of discrete memory, which flattens the comparison.

Finally, the AMD Radeon R6 M255DX achieves 4867 points, putting the RTX 3080 12 GB 1.6% behind. The R6 M255DX is a low-end mobile GPU, and a 1.6% deficit is not a meaningful performance indicator. In aggregate, these rival comparisons highlight that the benchmark's scoring is not representative of the RTX 3080's actual gaming or compute performance; the card's 26th percentile ranking across all GPUs is a more useful reference point.

Ray Tracing and Feature Set

The RTX 3080 12 GB includes 70 RT cores dedicated to ray tracing acceleration, a key feature for real-time reflections, shadows, and global illumination. Its 280 tensor cores handle AI-driven tasks such as deep learning super sampling, though specific DLSS version support is not detailed in the data. The card supports DirectX 12 Ultimate (12_2), which is the baseline for hardware-accelerated ray tracing and variable rate shading in modern titles, along with OpenGL 4.6 and Vulkan 1.4 for broad API compatibility. The FP32 and FP16 throughput are both listed at 30.64 TFLOPS (1:1 ratio), which is notable because it means the card does not halve FP16 performance as some architectures do, making it efficient for mixed-precision workloads. The 70 RT cores are fewer than what higher-tier Ampere cards offer, but they are sufficient for enabling ray-traced effects at playable frame rates when combined with the card's raw compute power. The 280 tensor cores, while not the top count in the lineup, provide the necessary hardware for AI-based features that can offload rendering work. Display output includes one HDMI 2.1 and three DisplayPort 1.4a connectors, supporting high-bandwidth displays. With a dual-slot form factor measuring 285 mm in length, 112 mm in height, and 40 mm in width, the card requires a spacious case, and its 1x 12-pin power connector means adapters may be needed for older PSUs. The production status is end-of-life, so availability is limited to existing stock, and the launch MSRP is 799 USD — a figure that reflects its positioning at the upper end of the 30-series stack at release.
