The Gigabyte Radeon RX 9070 GAMING OC 16G is AMD’s second-highest-tier flagship graphics card, offering an excellent balance between performance, efficiency, and affordability compared to the top-tier RX 9070XT. Built on AMD’s latest RDNA 4 architecture, it brings improved ray tracing, AI acceleration, and power efficiency. With Gigabyte’s custom design, including enhanced cooling and factory overclocking, this card promises great performance for gamers and content creators alike.
Gigabyte’s RX 9070 GAMING OC follows a familiar design, featuring a triple-fan WINDFORCE – Hawk fan cooling system with an extended heatsink for better thermal management. The card is robust, with a reinforced backplate and a subtle yet stylish RGB-lit Gigabyte logo on the side. Despite its powerful hardware, the card maintains a sleek 2.5-slot profile, making it easier to fit into most mid-tower cases compared to bulkier flagship models.
AMD RDNA 4 Architecture
The new Radeon RX 9070 XT and RX 9070 GPUs are powered by the 4 nm Navi 48 silicon, which differs from its predecessors, Navi 31 and Navi 32, by adopting a traditional monolithic die. Built entirely on TSMC’s N4P (4 nm EUV) process, the Navi 48 measures 356.5 mm² and boasts an impressive 53.9 billion transistors. For comparison, the previous flagship Navi 31, which powers the RX 7900 XTX, has 57.8 billion transistors—just 8% more—despite featuring 96 compute units (CU), a larger Infinity Cache, and a wider 384-bit memory bus. Navi 31’s total die area is 529 mm² (comprising a 304 mm² 5 nm graphics compute die and 6 nm memory cache dies), highlighting AMD’s advancements in die-area efficiency.
At the architectural level, the Navi 48 supports a PCI-Express 5.0 x16 interface and features a 256-bit wide GDDR6 memory bus. The RX 9070 XT utilizes 20 Gbps GDDR6 memory, delivering 640 GB/s of bandwidth, complemented by a faster 64 MB Infinity Cache and AMD’s new Out-of-Order Memory Queuing technology, which enhances memory management.
Physically, the Navi 48 silicon consists of 64 CU spread across four shader engines. Each CU houses 64 stream processors, resulting in a total of 4,096 stream processors. The RX 9070 XT has all 64 CU enabled, whereas the RX 9070 has 56 active CU out of 64. The fully unlocked Navi 48 features 4,096 stream processors, 128 AI accelerators, 64 ray tracing accelerators, 256 texture mapping units (TMUs), and 128 render output units (ROPs). It also includes 64 MB of third-generation Infinity Cache and a 256-bit GDDR6 memory interface, driving 16 GB of 20 Gbps memory on both the RX 9070 XT and RX 9070. With 56 CU enabled, the RX 9070 has 3,584 stream processors, 112 AI accelerators, 56 RT accelerators, 224 TMUs, and retains the full 128 ROP count, along with the same memory configuration as the RX 9070 XT.
At the core of the RDNA 4 graphics architecture is the newly designed dual compute unit (CU), featuring significant advancements in memory management, scalar unit efficiency, and engine clock optimizations. Key innovations include a vastly improved memory sub-system, dynamic register allocation, and enhancements to CU efficiency.
Each CU consists of two scheduler blocks controlling a 192 KB general-purpose register (GPR), an 8 KB scalar GPR, 32 fused multiply-add (FMA) ALUs, and 32 FMA+INT ALUs, along with 8 transcendental logic units. RDNA 4 introduces dual SIMD32 vector units, enabling greater parallelism. The scalar unit now supports newer Float32 operations, while schedulers benefit from accelerated spill/fill operations and improved instruction prefetching.
The new generation AI Accelerator integrates two 16-bit and four 8-bit/4-bit dense matrix compute rates, supports 4:2 structured sparsity to double throughput, and enables matrix loads with transpose. AMD has incorporated multiple technologies from its CDNA 3 Radeon Instinct AI ML accelerators, including enhanced and power-optimized WMMA, increased operations per CU, and support for FP8, E4M3, and E5M2 formats, alongside 4:2 structured sparsity improvements.
The next-generation AI Accelerator in RDNA 4 features two 16-bit and four 8-bit/4-bit dense matrix compute rates, along with support for 4:2 structured sparsity, effectively doubling throughput. It also introduces matrix loads with transpose for enhanced efficiency. AMD has integrated several advanced technologies from its CDNA 3 Radeon Instinct AI ML accelerators into RDNA 4’s AI engines, including optimized and power-efficient WMMA, increased operations per CU, and expanded support for FP8, E4M3, and E5M2 formats, alongside 4:2 structured sparsity enhancements.
The Navi 48 features a dual media engine, with each engine capable of performing concurrent encoding and decoding. This implementation is similar to NVIDIA GPUs, which have dual NVENC and NVDEC units. The new-generation media engine delivers a 25% improvement in H.264 low-latency encode quality and an 11% boost in HEVC encode quality. Additionally, AV1 encode and decode now support B-frames, significantly enhancing bitrate efficiency. Overall, the media engine offers a 50% generational performance uplift in encoder/decoder frame rates, while also reducing memory overhead.
