AMD is introducing a new chipset architecture, identical to what it is doing with its Ryzen CPUs. The Graphics Compute Die (GCD) is positioned among 3 MCD (Memory Cache Die) on every side. The Graphics Compute Die is 5 nanometers, whereas the Memory Cache Die is 6 nanometers. This method enabled AMD to achieve up to a 15 percent frequency range while improving power usage by up to 54 percent. This also assisted AMD in lowering the price of its Graphics Processing Units. In contrast to NVIDIA RTX 4090 GPUs, which employ the more pricey TSMC 4N fab technology, AMD was able to make savings by adopting 5 nanometers and 6 nanometers processors.

GPU Core

The NVIDIA RTX 4090 is built on TSMC’s 4N, a customized 5nanometers fab technology with an AD102 Graphics card at its core. The AMD RX 7900 XTX features 12,288 streaming units, which is not exactly analogous. In the meantime, the NVIDIA RTX 4090 features 16,384 CUDA cores.

GPU Memory

On the RTX 4090, NVIDIA incorporates relatively fast GDDR6X memory. AMD continues to use GDDR6. The memory access of the AMD RX 7900 XTX is the same as that of the NVIDIA RTX 4090, which is 24 Gigabytes. The AMD RX 7900 XT offers a larger memory capacity of 20 Gigabytes and quicker GDDR6X memory.

Clock Speed

Sorry, there are no Graphics processing units in this architecture that can reach a clock speed of 3 gigahertz. Perhaps faster-clocked Graphics cards will appear in the following generation.

Power Efficiency & Connectors

The AMD RX 7900 XTX has a total board capacity of 355W in terms of efficiency and power. These figures are smaller than those of the NVIDIA RTX 4090 TGP. AMD did not follow NVIDIA’s lead and did not adopt the 12VHPWR sixteen pin PCIe power cable. Rather, they use the standard eight pin PCIe power connections. AMD appears to be more economical than NVIDIA’s RTX 40 class graphics cards. AMD adopted DisplayPort 2.1 instead of the newest 16-pin PCIe power supply. This was one of AMD’s peak points. NVIDIA’s RTX 40 class graphics cards do not support the speedier DisplayPort 2.1 connection, instead opting for DP1.4a.

When the newest 8K displays are available, DisplayPort 2.1 should provide additional bandwidth. However, the AMD RX 7900 XTX will not be preferred for 8K gameplay. The majority of gamers nowadays still use 1080p and 1440p displays. 4K isn’t even the “standard” display for gamers. In any case, whether integrating DisplayPort 2.1 connections on the graphics card is advantageous or not will be determined after the new displays are introduced.

Gaming Performance

Generally, the AMD RX 7900 XTX is 1.5 – 1.7x faster at 4K than the previous generation. The AMD RX 7900 XTX is only a few percent slower than the NVIDIA RTX 4090, but it costs less. The AMD RX 7900 XT isn’t as quick, but it is less expensive and has a lower cost per frame.

The NVIDIA RTX 4090’s higher TDP requires the use of larger cooling fans. This indicates that the most expensive Ada GPU is much larger. In terms of heaviness, this is best demonstrated by comparing the older Nvidia versions to the AIB partnership cards. When we consider Gigabyte’s premium models, it’s clear how much larger we’re dealing with the NVIDIA RTX 4090. Because the chiller is almost twice as thick, you’ll need a complete high-rise PC case or some major headroom in your frame to manage its bulk and weight.

The dimensions of the NVIDIA RTX 4090 GPU are 358.5 Length, 162.8 Width & 75.1 Height in millimeters. In contrast, the AMD RX 7900 XTX has recently been verified to be a 2.5 slotted Graphics card rather than a 3 slot (thinner) GPU with an overall length of 287 millimeters. That’s a full 71milimetres shorter (approximately a 19 percent reduction). This is similar in size to the older RX 6950 XT. Therefore, if you have limited room inside your chassis, you won’t have to struggle as much with AMD’s newest release. Making things easy is absolutely good practice from AMD.

AMD RX 7900 XTX Vs NVIDIA RTX 4090 Breaking Down The Differences Between

The main goal of NVIDIA’s higher Ada price is straightforward: improved performance for a higher price. Finally, the efficiency is quite good and represents a significant improvement over Ampere. Furthermore, no one is unaware of the price and accessibility concerns. RDNA3 takes a different method. For the exact same cost, you get even more horsepower than the previous generation, although it is still weaker than NVIDIA’s Ada.

Ada vs RDNA3 Price to Performance

Finally, NVIDIA’s Ada is designed for people who require the most up-to-date features as well as lightning-fast performance.  AMD’s RDNA3 is designed for individuals looking for a reasonable performance boost while blowing the budget. You get roughly 20 percent less efficiency for 60 percent less money. In terms of capability, AMD has not revealed much, and we may see AMD putting up some real challenges for NVIDIA’s DLSS 3.0.

What Is The Main Difference Between DLSS 3 & FSR 3?

The DLSS 3 & FSR 3 are Artificial intelligence super sampling technology built into each GPU’s chip. Nvidia’s most recent edition includes Frame Generation along with 4 TensorFlow Cores. AMD’s response to the technology is known as Fluid Movement Framework Technology. They operate in a similar technique. When tone mapping the image quality, the Ai system produces precise frames to cover gaps.

Which Graphics Processing Unit Is Better (AMD RX 7900 XTX Vs NVIDIA RTX 4090

The NVIDIA RTX 4090 appears to be the winner in terms of pure technological prowess. We wouldn’t even be surprised if Nvidia’s card outperformed AMD’s latest offering in a head-to-head comparison, although we can’t say for sure. Your usage will be controlled by the volume of your power source and chassis, as the AMD RX 7900 XT might be more appropriate.

Will the AMD RX 7900 XTX do Well in Ray Tracing?

AMD was clearly playing capture with its initial-generation ray tracing processors present in the prior generation. The second version of this technology, however, will be featured in RDNA 3 chips, and the findings are significantly more encouraging. Whereas the ray tracing is unlikely to be as excellent as that found on Nvidia’s card, what we’ve seen thus far looks solid.
