The ultimate Ada Lovelace GPU: delivering a massive performance leap for 4K gaming and creative workloads with 24 GB of GDDR6X memory and AI-accelerated DLSS 3.

This is the NVIDIA GeForce RTX 4090, launched October 12, 2022, with an MSRP of $1,599.00 (USD). It is built on the Ada Lovelace architecture, packing 16,384 CUDA Cores and 24 GB of high-speed GDDR6X memory on a 384-bit bus. The card delivers exceptional performance: expect up to 2x the ray tracing speed via 3rd-Gen RT Cores and a 4x performance boost in supported titles using AI-powered DLSS 3 (4th-Gen Tensor Cores). It is engineered for ultra-high-resolution 4K gaming at max settings and demanding creator applications.

### [Speedup ML training with INT8](https://singapore.aitinkerers.org/talks/rsvp_psQ-nCEzNaY)

This talk explores using INT8 Tensor Cores in recent NVIDIA GPUs to accelerate training of transformer models. Benchmark results show up to 70% speedup on 4090 and 40% speedup on A100 compared to BF16 with minimal accuracy degradation.
