RTX 4090 vs 2080 Ti: What’s the Difference?

While both GPUs are impressive in their own right, they offer vastly different levels of performance due to their distinct architectural designs. We’ll now take a deeper look at what sets them apart and how those architectural differences bring about the disparity in performance. 

Graphics Processor

The RTX 4090 boasts a staggering 16,384 cores, which allows it to handle an enormous number of operations simultaneously. In comparison, the RTX 2080 Ti has respectable 4352 CUDA cores, but it simply can’t match the raw computing power of its newer counterpart. If you’re a professional content creator who’s always streaming content or a hardcore gamer, investing in an RTX 4090 could be a game-changer for your work or play. 

The 4090’s enhanced processing capabilities also dramatically improve performance in tasks that require large amounts of data processing, such as video rendering or scientific simulations. Besides its impressive core count, the RTX 4090 is equipped with a state-of-the-art ray tracing technology, allowing it to render hyper-realistic lighting and shadow effects in real-time.

Shader Cores, TMUs, and ROPs

The RTX 4090 and RTX 2080 Ti differ in terms of their shader cores, texture mapping units (TMUs), and raster operation pipelines (ROPs), all of which contribute to a GPU’s overall performance. The RTX 4090 boasts an impressive 512 4th generation Tensor cores, and 512 TMUs, making it one of the most powerful GPUs available. In contrast, the RTX 2080 Ti has 544 Tensor cores and 272 TMUs. Though still a formidable setup, it can’t match the sheer number of shader cores on the 4090.

The high number of TMUs and Tensor cores on the RTX 4090 allows it to excel at ray tracing and AI tasks, while the additional TMUs enhance its texture mapping capabilities. Moreover, the RTX 4090 has 176 ROPs, twice more than the RTX 2080 Ti, giving it an edge in rasterization performance. In practical terms, the 4090 can deliver smoother and more detailed graphics in demanding games and applications.

Bus Width

A wider bus can greatly improve a GPU’s memory bandwidth, allowing it to transfer data to and from the GPU’s memory faster. The RTX 4090 boasts a 384-bit memory bus, which is wider than the RTX 2080 Ti’s 352-bit bus. This means the RTX 4090 can move data through the memory subsystem more quickly and efficiently.

The wider memory bus on the RTX 4090 further allows it to handle more memory-intensive tasks, such as rendering high-resolution images or working with large datasets in scientific applications without slowing down.

GPU Memory and Clock Speeds

RTX 4090 has twice the memory of the 2080 Ti. It features 24 GB of GDDR6X VRAM, compared to the 2080 Ti’s 11 GB of GDDR6 memory. The  RTX 4090’s GDDR6X memory technology provides higher bandwidth, allowing it to process data quickly. 

The 4090 additionally has a base clock speed of 2.2 GHz and a boost clock speed of 2.5 GHz, which are significantly higher than the RTX 2080 Ti’s base clock of 1350 MHz and boost clock of 1545 MHz. The higher clock speeds of the RTX 4090 enable it to perform more calculations per second, leading to improved performance and faster rendering times.

The boost clock speed of a GPU is particularly important for gaming and other graphics-intensive applications. This is because the boost clock speed is the maximum frequency the GPU can achieve under load. The higher the boost clock, the faster the GPU can perform when needed, resulting in smoother gameplay and improved graphics quality.

Texture Fill Rate

Texture fill rate refers to the number of texture elements that can be processed per second. It’s an important consideration in gaming, as it impacts the quality of textures, shadows, and other visual effects. High texture fill rates can lead to more realistic and detailed graphics and more immersive gameplay experiences. A higher texture fill rate can also reduce visual artifacts like flickering and aliasing, resulting in smoother and more polished graphics.

The RTX 4090 has an impressive texture fill rate of 1.07 GTexel/s, more than three times the RTX 2080 Ti’s rate of 308.3 Gtexel/s. This means the RTX 4090 can handle more texture data simultaneously. The result? Better image quality and faster rendering times.

Floating-Point Performance

If you often have intensive computation workloads, floating-point performance is one of the most important metrics to consider. The RTX 4090 boasts a whopping 143.4 TFLOPS of floating-point performance, more than ten times the 13.4 TFLOPS of the RTX 2080 Ti. This makes the RTX 4090 an ideal choice for tasks requiring many numerical calculations, such as scientific simulations, 3D rendering, or deep learning

With such impressive performance, the RTX 4090 can deliver ultra-smooth and responsive visuals even in the most demanding scenarios. For a professional content creator or an avid gamer looking for the ultimate graphics experience, the RTX 4090’s floating-point performance is sure to impress.

Power Consumption

The RTX 4090 certainly packs a punch with its TDP of 450W. It’s no secret that high-performance graphics cards are power intensive, and the RTX 4090 is no exception. To put this into perspective, the RTX 2080 Ti has a TDP of 260W, significantly less than the RTX 4090. 

While the increased power consumption is necessary to power the impressive performance of the RTX 4090, remember that you’ll need a high-end power supply to handle this kind of power draw. It’s also worth noting that increased power consumption can lead to more heat output. So, it’s essential to ensure that your cooling system is up to the task before using RTX 4090 for intensive tasks such as gaming or video editing.

Size and Connectivity

The RTX 4090 is an absolute behemoth compared to the RTX 2080 Ti. Measuring 314mm x 160mm x 70mm, the RTX 4090 is considerably larger than its predecessor, the RTX 2080 Ti, which measures 267mm x 116mm x 40mm. The RTX 4090 also requires three 8-pin power connectors, while the RTX 2080 Ti only needs two. In terms of connectivity, the RTX 4090 features two HDMI 2.1 ports, three DisplayPort 1.4a ports, and one VirtualLink port, while the RTX 2080 Ti has one HDMI 2.0b port, three DisplayPort 1.4 ports, and one VirtualLink port. The additional ports on the RTX 4090 offer greater flexibility for users who need to connect multiple displays or VR devices to their graphics card.

Gaming Benchmarks

The RTX 4090 clearly outperforms the RTX 2080 Ti, with performance improvements of around 80%, according to reliable sources such as Passmark and reputable YouTube reviewers like Testing Games and Benchmark PC Tech

With numerous gaming tests conducted at higher resolutions like 1440p and 4K, these benchmarks suggest that 4090 can achieve significantly higher frame rates and smoother gameplay than its predecessors. This makes it an excellent choice for demanding AAA games and professional content creation tasks. 

Although individual results may vary depending on system specs and optimization settings, the overall gaming performance of the RTX 4090 is considered top-of-the-line, offering a premium experience for the most advanced gamers and graphics designers.


As we’ve already seen, the 4090 is one of NVIDIA’s top-of-the-line cards with a price tag that reflects its performance and capabilities. On the other hand, the 2080 Ti is still a very powerful card, but it has been surpassed by newer and more advanced models. Depending on the retailer, the price difference between the two cards can range from several hundred to thousands of dollars. As with any purchase, it’s important to consider your budget, intended use, and required performance before buying either.
