AMD's 4GB RX 9050 Trap: Hardware Unboxed Calls It the Most Deceptive GPU Ever

AMD introduced its lowest RDNA 4 card in July, the Radeon RX 9050, floating a $280 US price that never turned into US retail availability; in Japan it listed around 54,000 yen, about $345, while Australia had no retail stock at all. Hardware Unboxed host Steve says he spent about 1,700 Australian dollars through indirect channels to secure the 4GB model, because it is sold only inside complete OEM PCs and cannot be bought as a standalone boxed GPU, which already hints at how deliberately hidden the product is.

Same Name, Half the Bus: From 128-bit to 64-bit

The Navi 44 die natively supports a 128-bit memory bus, and the 8GB retail card fills it with four 2GB GDDR6 chips to deliver 288 GB/s and 32MB of Infinity Cache. To make a 4GB card AMD can only fit two 2GB chips, so the bus collapses to 64-bit, bandwidth halves to 144 GB/s and the cache drops to 16MB, a configuration that matches the old RX 6500 XT 4GB cards and cuts both capacity and speed at once.

The OEM trick is in the listing. The CyberPowerPC Gamer Master desktop sold at Best Buy advertises AMD Radeon RX 9050 graphics, with a small note of 4GB GDDR6 dedicated memory that most buyers will not decode; there is no mention of the halved bus or bandwidth, so research for RX 9050 inevitably surfaces benchmarks for the faster 8GB model and its official product page claims around 60 FPS in 007 First Light, nearly 100 FPS in Cyberpunk 2077 on medium, and over 200 FPS in Rainbow Six Siege, numbers the 4GB card cannot reach.

AMD's handling of review samples adds to the controversy. Hardware Unboxed says AMD told partners not to sample RX 9050 to reviewers and therefore sourced its 8GB and 4GB cards through side channels, unable to show the board or box or name the source. Coverage from VideoCardz and OC3D corroborates that the 8GB card was meant for limited retail in Latin America, Asia Pacific and Japan, while the 4GB was confirmed as a single-OEM special with half the interface, from 128-bit to 64-bit and 288 GB/s to 144 GB/s, and it was never intended for separate sale.

Crashing Even at the Lowest Settings

Steve deliberately gives the 4GB card its best chance: a modern GPU test bench with a Ryzen 7 9800X3D, PCI Express 5.0 and fast DDR5 memory, both of which soften the penalty when VRAM spills to system memory, and every game is run at 1080p on the lowest possible preset. He compares the 4GB and 8GB RX 9050 against the Intel Arc B570 10GB and both 4GB and 8GB RX 6500 XT cards across many titles, using two quality levels to separate bandwidth loss from capacity loss.

Forza Horizon 6 shows the scale quickly: on medium the 8GB RX 9050 is 47% faster than the 4GB, on very low 40% faster, while the Arc B570 is 32% ahead on medium with 116 FPS average that allows higher settings. Assassin's Creed Black Flag is about 45% faster on both low and ultra-low, and The Last of Us Part Two Remastered is 31% to 36% faster on the 8GB, with the Arc B570 about 38% faster. Crimson Desert is the tell: the 4GB and 8GB 6500 XT tie, so the game stays under 4GB, yet the 8GB 9050 is still 31% faster on low and 15% faster on minimum, proving the deficit is bandwidth, not capacity, and it will affect every game.

Resident Evil Requiem is roughly 38% faster on the 8GB at low and lowest, while the Arc B570 trails less in that title. 007 First Light is brutal: the 4GB RX 9050 manages only 38 FPS on its lowest preset, the 8GB is 53% faster, and the Arc B570 at 59 FPS is 55% faster with 96% better 1% lows, leaving the only path to 60 FPS on the 4GB as FSR Balanced upscaling that looks horrid at 1080p. F1 25 remains playable on low hardware, but the 8GB is 41% to 45% faster at 134 FPS versus the Arc B570 at 202 FPS, a 51% lead that shows headroom for higher visuals.

City Skylines 2 exposes the same bandwidth wound: while the 6500 XT pair ties, the 8GB 9050 is 35% faster on low and 66% faster on very low, with the Arc B570 44% to 69% ahead of the 4GB. Space Marine 2 on medium is 48 FPS versus 70 FPS, about 46% faster for the 8GB, and 81 FPS versus 70 FPS on low, about 37% faster; the 6500 XT 8GB also beats its 4GB sibling by 26% on low, confirming capacity still matters there. Cyberpunk 2077 Phantom Liberty is the narrowest gap at 74 FPS versus 80 FPS on medium, just 8% faster for the 8GB, but the Arc B570 dominates at 98 FPS, 22% ahead of the 8GB.

Proof in One Frame: Rainbow Six Siege

Rainbow Six Siege is the single-frame proof. On high at 1080p the 8GB RX 9050 averages 180 FPS versus just 111 FPS on the 4GB, a 62% gap, and on low 243 FPS versus 180 FPS, still about 35% faster, while the Intel Arc B570 tops the chart at 192 FPS. The 4GB and 8GB 6500 XT both average exactly 92 FPS in the same test, so the game uses well under 4GB, closer to 2GB, and suffers no capacity spill. The RX 9050's collapse therefore comes purely from the halved memory bandwidth, and that isolates AMD's naming decision as a technical deception rather than a simple capacity tier like the RX 9060 XT 8GB versus 16GB.

Other competitive titles follow the same split. Counter-Strike 2 on medium is 25% faster on the 8GB well above 300 FPS, with the Arc B570 at 368 FPS and then 400 FPS on low, while the 6500 XT pair ties at 213 FPS to underline bandwidth as the limiter. Battlefield 6 on medium is 71 FPS versus 98 FPS, about 38% faster for the 8GB and 115 FPS for the Arc B570, 17% ahead of the 8GB, and on low 123 FPS for the B570 versus a 29% lead for the 8GB over the 4GB. Marvel Rivals mirrors Pragmata at 69-70 FPS on medium with a 43% lead for the 8GB over the 4GB, Pragmata itself is 31% faster on balanced and 20% on minimum, and Lego Batman is 42% faster on medium at 175 FPS versus the 4GB, with the 6500 XT 8GB nearly doubling the 4GB at 112 FPS versus 59 FPS.

Math on a $750 OEM Box and What Buyers Should Do

The price math on the OEM box clarifies the value case. The $750 CyberPowerPC includes a Ryzen 5 5500, a single 8GB DDR4 stick, an AM4 Micro ATX board, a 500GB SSD and the 4GB RX 9050, and Steve prices the parts at retail: the CPU about $80, the memory stick about $50, the board about $70, the SSD about $80, case and power supply under $100, and a tower cooler about $20, for roughly $400 in hardware before Windows 11 Home and profit. That leaves about $350 for the GPU, the OS and margin, implying AMD sells the 4GB RX 9050 for at least $250 even at OEM pricing, essentially the same as the $260 retail Intel Arc B570 that is on average 44% faster in these tests and carries 10GB VRAM.

The 18-game averages sum it up, each title showing the same wound. On the 1080p low preset the Intel Arc B570 10GB averages 112 FPS, about 5% ahead of the 8GB RX 9050, while the 8GB RX 9050 is a staggering 37% faster than the cut-down 4GB OEM, and on the lowest preset the 8GB is still 32% faster at 147 FPS versus the Arc B570. Steve notes this understates the real pain, because the bench uses PCI Express 5.0 and DDR5, and his next video will test the 4GB card inside the actual CyberPowerPC with PCI Express 3.0 from the Ryzen 5 5500 and single-channel DDR4, where spilling out of VRAM will be far more brutal and even RTX-class memory pressure from RTX 4090 and RTX 5090 shows how tight the market is. The RTX comparison matters because even high-end RTX cards feel memory cost, and a new 4GB card in 2026 has no credible future.

The verdict in the video is blunt and data-backed: the 4GB RX 9050 is a scam and should have been called RX 9040, because sharing the exact same product name while halving bandwidth and hiding the card as an OEM exclusive is designed to confuse buyers who research the faster 8GB results. It technically runs games, but at low, medium and even minimum presets it trails by 30% to 62% depending on the title, and in a modern AAA game like 007 First Light it cannot reach 60 FPS at 1080p without upscaling that looks terrible. For anyone facing an OEM listing that says RX 9050, the practical move is to check the memory line for 4GB versus 8GB, prefer an Intel Arc B570 or a used 8GB card at the same budget, and treat any budget GPU with 4GB VRAM and a 64-bit bus as a bad deal regardless of the chip inside, because in 2026 the memory and chip supply now decides the gaming experience more than the logo on the box.
