Below is the detailed discussion based on the rumors and leaks circulating about the NVIDIA RTX 5090:

Memory Upgrade

One of the most significant rumors, corroborated by multiple leaks, suggests the RTX 5090 will be equipped with a staggering 28GB of GDDR7 memory, a substantial leap from the 24GB GDDR6X found in the RTX 4090. This increase in memory capacity would cater to the ever-growing demands of high-resolution gaming at increasingly demanding frame rates. It would also benefit professionals working with massive datasets in applications like video editing and 3D rendering.

Memory Bus Bandwidth

Another prominent rumor involves the memory bus. According to leaks, the RTX 5090 might come equipped with a massive 448-bit bus, compared to the 384-bit bus of its predecessor. This wider data pathway between the GPU and memory could lead to significant performance gains in memory-intensive workloads.

Core Specification Upgrades

When it comes to core specifications, the rumors indicate some monstrous upgrades. Leaks suggest the RTX 5090 will pack 192 Streaming Multiprocessors (up from 128 on the 4090), a whopping 24,576 CUDA cores (up from 16,384), 192 Ray Tracing cores (up from 128), and 768 Tensor cores (up from 512).

Increased Clock Speeds

The alleged leaked clock speeds also show a boost, with the RTX 5090 purportedly reaching up to 2.9GHz, compared to 2.52GHz on the 4090.

Cache and Bandwidth Improvements

Feeding this power is rumored to be a massive 128MB of L2 cache (up from 72MB) and blistering 1.5TB/s memory bandwidth (up from 1TB/s).

New Architecture

Under the hood, leaks indicate the RTX 5090 will be powered by the "GB202" chip is rumored to be manufactured on TSMC's 3nm or 4nm process node based on Nvidia's new "Blackwell" architecture. This promises substantial improvements in performance-per-watt efficiency over the previous "Ada Lovelace" architecture.

Multi-Chip Module Design

To accommodate these increased component counts, multiple rumors suggest Nvidia will employ an innovative multi-chip module (MCM) design for the RTX 5090 Founder's Edition. Leaked details claim the PCB will be split into three sections - the main board, a dedicated rigid I/O board, and the PCIe slot acting as a riser.

Dense Memory Configuration

Adding to the intrigue, one leak describes the RTX 5090 utilizing a very dense configuration with 16 memory modules. This unique layout could potentially enable the use of a surprisingly slim dual-slot, dual-fan cooler design rather than a bulkier solution.

Monolithic GPU Die

While leakers agree the RTX 5090 will utilize a multi-chip module board design, they also suggest Nvidia will stick with a monolithic GPU die rather than implementing a chiplet-based architecture. 

Massive Performance Gains

In terms of performance, while official benchmarks are still pending, one prominent leak states the RTX 5090 could deliver up to an incredible 70% increase in raw rasterized performance compared to the powerhouse RTX 4090. With its rumored architectural and specification advancements, the 5090 is anticipated to push the boundaries of what's possible across the board, from ultra-high 8K resolution gaming to major advances in real-time ray tracing effects. For professionals, the RTX 5090 could offer rendering times that simply demolish the previous generation.

New Display and Power Connector Support

On the features front, leaks indicate the RTX 5090 will support the latest DisplayPort 2.1 specification for enabling higher resolutions and refresh rates than previous display output standards. There are also rumors that Nvidia may introduce an all-new 16-pin power connector design to replace the troubled 12VHPWR standard used on the RTX 4090, which suffered from melting issues for some unlucky users.

Release Timeframe

When it comes to availability, most leaks point to the RTX 5090 launching in Q4 2024, approximately two years after the RTX 40 series debuted. However, there is conflicting information on whether it or the RTX 5080 will be the first card in the new lineup to hit the market.

The NVIDIA RTX 5090, even in its rumored form, represents the relentless march of technological progress in the realm of graphics cards. With its potential for groundbreaking performance and exciting new features, it promises to lead a new era of immersive gaming experiences and empower professionals to create stunning visuals and complex simulations.
