NVIDIA GeForce GTX 1660 Ti Mobile in 2025: Is It Worth It?

Overview of the mobile GPU for gamers and professionals

1. Architecture and Key Features

Turing: The Foundation Without RTX Excesses

The GTX 1660 Ti Mobile graphics card is built on the Turing architecture, which debuted in 2018. Despite its age, this architecture remains relevant due to its gaming optimization and energy efficiency. The manufacturing process is 12 nm (TSMC), which seems modest for 2025, but provides a balance between performance and heat generation.

What Can It Do, and What Can't It?

The main difference between the GTX series and RTX is the absence of dedicated RT cores and tensor cores. This means ray tracing (RTX) and DLSS are not available. However, NVIDIA offsets this with support for technologies like Adaptive Shading and improved anti-aliasing algorithms. For some games, AMD's FidelityFX Super Resolution (FSR) is available, which works on any GPU, including the GTX 1660 Ti.

2. Memory: Speed vs. Size

GDDR6: 6 GB for 1080p

The card is equipped with 6 GB of GDDR6 memory on a 192-bit bus. The bandwidth is 288 GB/s, which is sufficient for most games at Full HD. However, by 2025, even 6 GB becomes a bottleneck in projects with ultra textures (e.g., "Cyberpunk 2077: Phantom Liberty" or "Starfield").

Tip: For comfortable gaming, turn off "Ultra" textures—the difference between "High" and "Ultra" at 1080p is almost negligible, and memory load will decrease by 20-30%.

3. Gaming Performance

Full HD: The Ideal Option

In 2025, the GTX 1660 Ti Mobile remains a “mid-range” choice for 1080p:

- Cyberpunk 2077 (medium settings): 45-50 FPS;

- Valorant (maximum settings): 160-180 FPS;

- Hogwarts Legacy (high settings): 35-40 FPS (with FSR 2.0 — up to 55 FPS);

- Fortnite (epic settings): 70-80 FPS.

1440p and 4K: Is It Worth Trying?

At QHD (2560x1440), the card only manages less demanding games (CS:GO, Dota 2) or when FSR is actively used. 4K is reserved for top-tier GPUs, and the GTX 1660 Ti Mobile is not competitive here.

Ray Tracing: Only Through Mods

Hardware RTX ray tracing is unavailable, but in some games (like "Minecraft"), enthusiasts enable it through third-party patches. The result: 15-20 FPS—more of an experiment than practical use.

4. Professional Tasks

CUDA in Action

The 1536 CUDA cores in the GPU are useful in programs like Adobe Premiere Pro or Blender. Rendering a 30-minute video in 1080p takes about 40-50 minutes (compared to 25-30 minutes for the RTX 3050).

Memory Limitations

6 GB is insufficient for complex 3D scenes. For instance, rendering a model with 10 million polygons in Blender may cause stuttering. The card is suitable for study or hobby work, but professionals should look at the RTX 3060 (8-12 GB).

5. Power Consumption and Heat Generation

TDP 80W: Easy for Laptops

The GTX 1660 Ti Mobile does not require complex cooling systems. In gaming laptops (like the ASUS TUF or Lenovo Legion), the temperature rarely exceeds 75-80°C.

Cooling Tips:

- Use cooling pads with fans;

- Clean the coolers from dust once a year;

- Avoid working on soft surfaces (pillows, blankets).

6. Comparison with Competitors

NVIDIA RTX 3050 Mobile: The Younger Brother with RTX

The RTX 3050 (4 GB GDDR6) is weaker in pure performance but offers DLSS and RTX ray tracing. Price starts from $700 (laptops), while devices with the GTX 1660 Ti Mobile in 2025 can be found for $550-600.

AMD Radeon RX 6600M: An Alternative with FSR 3.0

The RX 6600M (8 GB GDDR6) is 15-20% faster in DX12 games and supports FSR 3.0 with frame generation. However, AMD drivers are less stable for professional tasks.

7. Practical Tips

Power Supply and Compatibility

- Laptops with GTX 1660 Ti Mobile usually require a power supply of 150-180W;

- For external monitors (up to 144 Hz), HDMI 2.0b or DisplayPort 1.4 is sufficient;

- Update drivers through GeForce Experience: in 2025, NVIDIA is still releasing optimizations for Turing.

8. Pros and Cons

Pros:

- Optimal for 1080p gaming;

- Low heat and power consumption;

- Affordable price (laptops from $550).

Cons:

- No hardware ray tracing;

- 6 GB of memory is low for modern AAA games;

- Inferior to new budget GPUs (e.g., RTX 4050 Mobile).

9. Final Conclusion: Who Should Consider the GTX 1660 Ti Mobile?

This graphics card is a choice for those who:

- Play at 1080p and are willing to lower settings in new projects;

- Are looking for an affordable laptop for work and study;

- Value a quiet cooling system.

Why Is It Still Relevant in 2025?

Despite the emergence of newer GPUs, the GTX 1660 Ti Mobile remains in the budget gaming solutions niche. Its performance is adequate for 60 FPS in 80% of games with proper settings, and its lower price compared to alternatives makes it a cost-effective option without significant compromises.

Prices are cited for new devices as of April 2025. When choosing, keep in mind that technology doesn't stand still, but "old proven" solutions sometimes turn out to be a wise investment.

Memory Bus

The memory bus width refers to the number of bits of data that the video memory can transfer within a single clock cycle. The larger the bus width, the greater the amount of data that can be transmitted instantaneously, making it one of the crucial parameters of video memory. The memory bandwidth is calculated as: Memory Bandwidth = Memory Frequency x Memory Bus Width / 8. Therefore, when the memory frequencies are similar, the memory bus width will determine the size of the memory bandwidth.

Bandwidth

Memory bandwidth refers to the data transfer rate between the graphics chip and the video memory. It is measured in bytes per second, and the formula to calculate it is: memory bandwidth = working frequency × memory bus width / 8 bits.

Miscellaneous

SM Count

Multiple Streaming Processors (SPs), along with other resources, form a Streaming Multiprocessor (SM), which is also referred to as a GPU's major core. These additional resources include components such as warp schedulers, registers, and shared memory. The SM can be considered the heart of the GPU, similar to a CPU core, with registers and shared memory being scarce resources within the SM.

Shading Units

The most fundamental processing unit is the Streaming Processor (SP), where specific instructions and tasks are executed. GPUs perform parallel computing, which means multiple SPs work simultaneously to process tasks.

The Raster Operations Pipeline (ROPs) is primarily responsible for handling lighting and reflection calculations in games, as well as managing effects like anti-aliasing (AA), high resolution, smoke, and fire. The more demanding the anti-aliasing and lighting effects in a game, the higher the performance requirements for the ROPs; otherwise, it may result in a sharp drop in frame rate.
