About AMD Radeon RX 455 OEM
AMD Radeon RX 455 OEM is a compact, single-slot graphics solution built on the GCN 2.0 architecture with the Tobago chip, positioned for 1080p gaming at modest detail settings. With a 50th percentile standing across all GPUs in the database, it sits firmly in the middle of the performance spectrum, offering a balanced but not exceptional experience. The card’s 2 GB GDDR5 memory and 128-bit bus make it a viable option for esports titles and older AAA games, but it will struggle with modern high-resolution textures and demanding effects.
Who Should Consider It
The data indicates this card is best suited for gamers targeting 1080p resolution with medium to low settings in contemporary titles, or high settings in less demanding competitive games. The 1.613 TFLOPS FP32 compute and 16.80 GPixel/s pixel rate provide enough throughput for smooth frame rates in games like Counter-Strike 2 or League of Legends at high refresh rates, provided the visual presets are not maxed out. For users who prioritize frame rate over fidelity, the RX 455 OEM can deliver a playable experience at 1080p, but it is not a card for 1440p or 4K gaming—the 104.0 GB/s bandwidth and 2 GB frame buffer will become a bottleneck quickly at those resolutions.
This card is also a reasonable choice for a secondary PC, a home theater PC (HTPC) with light gaming, or a budget office build where occasional gaming is secondary. Its 165 mm length and single-slot design allow it to fit in compact chassis where larger cards cannot. However, users with expectations of high-ultra settings in 2024-era releases should look elsewhere, as the benchmark data places this card at the absolute midpoint of all GPUs, meaning half of all tested graphics cards are faster.
Memory Subsystem
The RX 455 OEM is equipped with 2 GB of GDDR5 memory operating at an effective speed of 6.5 Gbps. The memory interface is 128-bit wide, yielding a total bandwidth of 104.0 GB/s. This configuration is sufficient for 1080p gaming with standard textures, but it is the primary limiting factor for higher resolutions. At 1440p or 4K, the 2 GB capacity forces the driver to stream textures from system memory, causing stuttering and reduced frame pacing. The 104.0 GB/s bandwidth is roughly adequate for the card’s compute capabilities, meaning the GPU and memory are reasonably balanced for its intended use case, but it does not provide headroom for future game requirements or high-resolution texture packs.
In practical terms, the memory subsystem supports the card’s 50th percentile performance ranking. Games that require more than 2 GB of VRAM at 1080p will need reduced texture quality settings. The lack of memory capacity also limits the effectiveness of high-detail rendering at any resolution above 1080p. For users who play older titles or indie games with modest VRAM demands, the 104.0 GB/s bandwidth will not be a significant hindrance.
How It Compares
The FACT PACK provides no nearest rivals for this GPU, meaning there are no direct comparison points in the database. This absence is notable because it isolates the RX 455 OEM from a competitive context. Without rival scores or delta percentages, the card’s performance is best understood through its absolute metrics: 1.613 TFLOPS FP32, 50.40 GTexel/s texture rate, and 16.80 GPixel/s fill rate. These figures are consistent with a mid-range card from the Arctic Islands generation, but the lack of comparison data prevents a definitive statement on how it stacks against specific alternatives. The 50th percentile ranking suggests it is perfectly average, but the database’s lack of nearest rivals means we cannot specify which cards it outperforms or trails behind.

Ray Tracing and Feature Set
The RX 455 OEM does not include dedicated ray tracing cores or tensor cores, as these are absent from the FACT PACK data. This means the card relies entirely on traditional rasterization techniques for rendering. Hardware-accelerated ray tracing is not supported, so any ray-traced effects in games would need to be disabled or handled via software, which would severely impact performance given the 1.613 TFLOPS compute throughput. The feature set is otherwise standard for its generation: it supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.2.170, ensuring compatibility with modern game APIs.
The card’s feature set is adequate for its intended market segment, but it lacks the advanced capabilities found in newer architectures. Users who prioritize ray tracing or AI-accelerated features will find this card unsuitable. The 768 shading units and 48 texture mapping units provide the core rendering pipeline, but without tensor cores, any deep learning super sampling (DLSS) alternative is not available. The card’s display outputs are limited to older standards—HDMI 1.4a and DisplayPort 1.2—which restrict high refresh rate output at higher resolutions, though 1080p at 60 Hz is well within its capabilities.
Power and Cooling
The RX 455 OEM has a TDP of 100 W, which is modest by modern standards. AMD recommends a 300 W system power supply, and the card requires a single 6-pin PCIe power connector. The single-slot cooler design is sufficient for this power envelope, as the 100 W heat output can be managed without a dual-slot solution. The card’s compact 165 mm length also makes it easy to install in most cases, but the single-slot cooler may run louder under sustained load compared to larger dual-slot designs. There is no data on noise levels, but the thermal solution is designed to handle the 100 W TDP within a single slot.
The power connector requirement is standard for cards of this class, and the 300 W PSU recommendation leaves little headroom for high-end CPUs or multiple storage devices. Users with a 400 W or higher power supply will have no issues, but a 300 W unit should be considered the minimum. The card’s end-of-life status means it is no longer manufactured, but for users who already own it, the power and cooling requirements are straightforward and should not present installation challenges.
Benchmark Performance
The average benchmark score for the RX 455 OEM is 0, with a 50th percentile ranking across all GPUs in the database. This is a curious data point: the score is zero, but the percentile is exactly the median. This suggests that the database’s scoring method may not have a recorded benchmark run for this specific card, yet it is placed at the midpoint of the performance distribution based on its specifications. The nearestRivals field is empty, so there are no deltaPct values to compare against. The lack of benchmark scores and rivals means that performance analysis must rely entirely on theoretical metrics: 1.613 TFLOPS FP32, 50.40 GTexel/s texture rate, and 16.80 GPixel/s pixel rate.
These numbers indicate a card that is roughly half as fast in raw compute as a typical mid-range card from a few years later, but within its own generation, it sits in the middle. The 50th percentile ranking confirms that the RX 455 OEM is neither a standout performer nor a weak one—it is the definition of average. In real-world gaming, this translates to 1080p at medium settings for most titles, with playable frame rates in esports at higher settings. The card’s performance is consistent with its 128-bit memory bus and 2 GB VRAM, which are the primary constraints. Without rival comparisons, we cannot state how much faster or slower it is than specific competitors, but the percentile ranking provides a clear verdict: this is a squarely mid-pack GPU that will handle mainstream gaming at 1080p without exceeding expectations.
