As anticipation builds for Nvidia's next-generation graphics cards, recent leaks have revealed significant details about the upcoming RTX 5090 series, suggesting substantial improvements in both power consumption and memory capabilities compared to its predecessors.
Power Requirements and Efficiency
The upcoming Nvidia RTX 5090 is reportedly set to draw 575W of power, marking a 125W increase from its predecessor, the RTX 4090. While this represents a considerable 30% increase in power consumption, it's actually lower than earlier rumors that suggested a 600W TDP. This power increase aligns proportionally with the reported 30% increase in CUDA cores, jumping from 16,000 to 21,600 cores.
| Specification | RTX 5090 | RTX 4090 | Change |
|---|---|---|---|
| TDP | 575W | 450W | +125W |
| CUDA Cores | 21,600 | 16,000 | +5,600 |
| Memory Type | GDDR7 | GDDR6X | New Gen |
Mobile Variant's Memory Innovation
In a surprising development, the mobile version of the RTX 5090 might feature 24GB of VRAM, utilizing new GDDR7 memory modules. This represents a significant advancement over current offerings, made possible by Samsung's development of 24Gb (3GB) GDDR7 modules capable of reaching speeds up to 42.5 Gbps. The mobile variant will reportedly use a 256-bit memory interface, with the higher-capacity modules helping to overcome this limitation.
| RTX 5090 Mobile Specs |
|---|
| Memory: 24GB GDDR7 |
| Memory Interface: 256-bit |
| Memory Module Size: 24Gb (3GB) |
| Memory Speed: Up to 42.5 Gbps |
Architecture and Memory Technology
The RTX 50 series, codenamed Blackwell, will be the first consumer GPUs to feature GDDR7 memory. This new memory technology promises improved speeds and density compared to GDDR6 and GDDR6X. While most models in the series will use 16Gb (2GB) modules, the potential use of 24Gb modules in the mobile variant suggests Nvidia is pushing boundaries in mobile graphics performance.
Market Implications
These specifications indicate Nvidia's commitment to pushing performance boundaries, even as they manage power consumption concerns. The reduced power draw from earlier rumors might suggest a more balanced approach to performance and efficiency. For users considering an upgrade, these developments warrant attention to power supply requirements, with several manufacturers already announcing PSU support for next-generation graphics cards.
