GIGABYTE debuts RTX 5070 with Blackwell architecture and GDDR7 memory

The transition to Blackwell and GDDR7 provides a significant lift for professional video workflows, particularly in AI-driven encoding and neural rendering. By integrating fifth-generation Tensor Cores and ninth-generation encoders, GIGABYTE is targeting the middle-market production tier where speed in 8K decoding and multi-frame generation is becoming a competitive necessity. This release reinforces NVIDIA’s dominance in the B2B creative hardware stack, forcing competitors like AMD to accelerate their own architectural refreshes. Watch for benchmark data on AV1 encoding efficiency compared to previous Ada Lovelace models to gauge the true ROI for high-volume streaming origin servers.

At CES 2025, NVIDIA officially unveiled the Blackwell-based RTX 50-series lineup, including the flagship RTX 5090 and the mid-range RTX 5070. According to reports from Tom’s Hardware in January 2025, the Blackwell architecture represents a major shift in graphics memory, moving to GDDR7 at speeds of 28 Gbps. This memory standard uses PAM3 signaling to achieve higher bandwidth and energy efficiency compared to the GDDR6X used in the previous generation. NVIDIA CEO Jensen Huang noted during the keynote that while the RTX 5070 targets a $549 price point, its AI performance is intended to rival the previous flagship RTX 4090 when utilizing the full DLSS 4 suite.

From a video production standpoint, the new ninth-generation NVENC supports professional-grade 4:2:2 chroma subsampling for AVC, HEVC, and AV1 formats. Per NVIDIA’s technical documentation from early 2025, this hardware-level support allows video editors to handle high-fidelity camera original footage directly on the GPU, a capability previously exclusive to Intel’s QuickSync engines. Additionally, the new 'Ultra High Quality' (UHQ) mode in the Blackwell encoder is reported to provide a 5% improvement in compression efficiency for HEVC and AV1 streams. These hardware advancements are being released alongside NVIDIA’s Video Codec SDK 13.0, which enables 2x throughput improvements for H.264 decoding on Blackwell silicon.
