For both technology enthusiasts and industry professionals, keeping a close eye on the latest GPU advancements isn't just a hobby – it's crucial for staying competitive and maximizing your performance and compute power. Here at, we're just as excited to witness the next big leaps forward in graphics technology!

Today, we're looking at two GPUs in particular: the formidable NVIDIA RTX 4090 versus its highly anticipated successor, the not-yet-released RTX 5090. While the RTX 4090 has solidified its reputation for performance, the RTX 5090 is still a subject of much speculation.

As we explore what we know and what we anticipate, keep in mind our knowledge of the RTX 5090 is still evolving. But nonetheless, let's take a look at the facts, the early insights, and emerging rumors…

Spotlight on NVIDIA GeForce RTX 4090

Known for being the fastest consumer-grade GPU on the market, the RTX 4090 is truly a beast of a machine. Based on the AD102 chip using the Ada Lovelace architecture, it epitomizes super-high-end gaming and professional performance.

The RTX 4090 has a triple-slot design and boasts an incredible 128 dedicated third-gen RT cores and 512 fourth-gen Tensor cores – more than its closest competitors – elevating ray-tracing performance and speeding up AI-driven tasks like DLSS 3 in games.

Plus, it's packed with 16,384 CUDA cores and has 24GB of GDDR6X graphics memory with a maximum bandwidth of 1,008 GB/s and a 384-bit memory bus interface. Error-correcting code (ECC) can be enabled, but this reduces performance while making no difference in GPU rendering – so keeping it turned off is appropriate for most uses when you're prioritizing speed.

Due to its immense processing capability, the RTX 4090 draws a lot of power to deliver maximum performance: 450 watts. It requires an 850-watt power supply and robust cooling solutions, which does increase usage costs, of course.

Launched in September 2022, the RTX 4090 still currently stands as the pinnacle of NVIDIA’s offerings for enthusiasts seeking unmatched graphics performance and computational power.

But that will change in due time.

Anticipating NVIDIA GeForce RTX 5090

The RTX 5090 is expected to be released later this year – and it's a game-changer, poised to redefine high-end performance with its groundbreaking features and next-gen architecture. That's right, we're now moving beyond NVIDIA's Ada Lovelace and into the era of the Blackwell architecture.

Joining the new Blackwell GPU lineup, the flagship GeForce RTX 5090 will reportedly utilize the "physically monolithic" GB202 die. Among its highlights are a potential 512-bit memory bus and up to 32GB of next-gen GDDDR7 memory (the successor to the GDDR6/X memory used by the RTX 40-series GPUs). Early reports suggest the RTX 5090 could achieve memory bandwidths of up to 1,532 GB/s, a substantial boost from the RTX 4090's 1,008 GB/s​.

Some are expecting to see up to 192 streaming multiprocessors (SMs) in the RTX 5090, with an unprecedented 24,576 CUDA cores – assuming the GB202 chip keeps the 128-cores-per-SM design as seen in the RTX 4090. Plus, rumors say the RTX 5090 will feature 192 third-gen RT cores and 768 fourth-gen Tensor cores, up from 128 and 512 respectively in the RTX 4090.

The RTX 5090 is anticipated to deliver 50-70% performance improvements across the board compared to the RTX 4090 – particularly excelling in 4K resolution. And with 4K 240FPS gaming on the horizon, the RTX 5090 will be perfectly positioned to tackle the most demanding gaming scenarios.

Some are also looking forward to seeing the RTX 5090 support next-gen DLSS 4, NVIDIA's AI-powered upscaling that will further enhance performance and image quality​.

In terms of power consumption, the RTX 5090 will likely follow the trend of its predecessors, with total graphics power (TGP) ranging from 450W to 600W, about on par with the RTX 4090.

For a quick look at some of the anticipated specs of the RTX 5090 compared to the RTX 4090 – based on the latest speculation and leaks – here's a table highlighting the upgrades:

Concluding Thoughts

As we anticipate the release of the RTX 5090, it's important to recognize that the RTX 4090 already delivers exceptional performance, handling everything available at 4K with ease. The RTX 5090, while sure to be extremely impressive, may be seen more as a luxury upgrade rather than a necessity for gamers and professionals who can (or already do) benefit from the power of the RTX 4090.

Cost is another critical factor. The RTX 5090 will undoubtedly be a top-of-the-line machine with a matching price tag. And the RTX 4090 is no slouch, either, still commanding a steep price to this day, nearly two years after its release.
