128-Bit vs 256-Bit GPU - Major Differences

1. Bandwidth:

The bandwidth of a 128-bit bus is 32 GB/s, while the bandwidth of a 256-bit bus is double that at 64 GB/s. So, if you’re looking for a card with higher bandwidth, you’ll want to go with a 256-bit card.

2. Clock speed:

3. Fill rate:

The fill rate of a 128-bit card is 21.3 Gigatexels/sec, while the fill rate of a 256-bit card is 42.6 Gigatexels/sec.

4. Memory size:

The memory size of a 128-bit card is 1 GB, while the memory size of a 256-bit card is 2 GB.

5. Memory bandwidth:

The memory bandwidth of a 128-bit card is 64 GB/s, while the memory bandwidth of a 256-bit card is 128 GB/s.

6. Pixel rate:

The pixel rate of a 128-bit card is 10.8 Gpixels/sec, while the pixel rate of a 256-bit card is 21.6 Gpixels/sec.

7. Texture rate:

The texture rate of a 128-bit card is 10.8 Gtexels/sec, while the texture rate of a 256-bit card is 21.6 Gtexels/sec. So, if you’re looking for a card with a higher texture rate, you’ll want to go with a 256-bit card.

8. Geometry rate:

The geometry rate of a 128-bit card is 1.8 GHz, while the geometry rate of a 256-bit card is 3.6 GHz.

9. shader model:

The shader model of a 128-bit card is 2.0, while the shader model of a 256-bit card is 3.0.

10. Pixel shaders:

The number of pixel shaders on a 128-bit card is 16, while the number of pixel shaders on a 256-bit card is 32. 

11. Vertex shaders:

The number of vertex shaders on a 128-bit card is 8, while the number of vertex shaders on a 256-bit card is 16.

12. Floating point performance:

A 128-bit card has a floating point performance of 1.8 TFLOPS, while a 256-bit card has a floating point performance of 3.6 TFLOPS, and there is little difference between the two. So, if you’re looking for a card with higher floating point performance, you’ll want to go with a 256-bit card

13. DirectX version:

The DirectX version supported by a 128-bit card is 9.0c, while the DirectX version supported by a 256-bit card is 10.0.

14. OpenGL version:

The OpenGL version supported by a 128-bit card is 2.0, while the OpenGL version supported by a 256-bit card is 3.0.

15. RAMDACS:

The RAMDAC of a 128-bit card is 400 MHz, while the RAMDAC of a 256-bit card is 600 MHz.

16. Max resolution:

The maximum resolution supported by a 128-bit card is 2048x1536, while the maximum resolution supported by a 256-bit card is 2560x1600.

17. VGA output:

A 128-bit card can support a maximum resolution of 2048x1536 on a VGA output, while a 256-bit card can support a maximum resolution of 2560x1600 on a VGA output.

18. DVI output:

A 128-bit card can support a maximum resolution of 1600x1200 on a DVI output, while a 256-bit card can support a maximum resolution of 1920x1200 on a DVI output.

19. HDMI output:

A 128-bit card can support a maximum resolution of 1080p on an HDMI output, while a 256-bit card can support a maximum resolution of 4K on an HDMI output.

20. DisplayPort:

A 128-bit card can support a maximum resolution of 2560x1600 on a DisplayPort, while a 256-bit card can support a maximum resolution of 4096x2160 on a DisplayPort. So, if you’re looking for a card that can support higher resolutions, you’ll want to go with a 256-bit card.

Cards with 256 bits are generally better than ones with 128 bits. They have higher bandwidth and clock speeds, more memory, and support higher resolutions. So, if you’re looking for a better-performing card, you should go with a 256-bit card.

Conclusion

So, what is the difference between 128-bit and 256-bit GPUs? The short answer is that a 256-bit GPU can process more data at once than a 128-bit GPU. This means that it can render graphics faster and handle higher-resolution displays with ease. If you are looking for a new gaming laptop or desktop, be sure to look for one with a 256-bit GPU. Alternatively, if you are looking to upgrade your current machine, consider swapping out your old 128-bit card for something newer and faster. Let us know in the comments section how you decide which type of GPU works best for you.

Frequently Asked Questions

What does 128-bit mean on a GPU?

A 128-bit GPU has a 128-bit memory bus. This means that it can transfer data to and from the VRAM at a rate of 128 bits per clock cycle. A 256-bit GPU has a 256-bit memory bus, which means it can transfer data to and from the VRAM at a rate of 256 bits per clock cycle. So, a 256-bit GPU is twice as fast as a 128-bit GPU.

What is the difference between 128 bit and 256-bit GPUs?

The main difference between 128 bit and 256-bit GPUs is the memory bus width. A 128-bit GPU has a 128-bit memory bus, while a 256-bit GPU has a 256-bit memory bus. This means that a 256-bit GPU is twice as fast as a 128-bit GPU. Additionally, a 256-bit GPU has twice the memory of a 128-bit GPU.

Is a 256-bit GPU good?

A 256-bit GPU is better than a 128-bit GPU. It has higher bandwidth and clock speeds, more memory, and support for higher resolutions. So, if you’re looking for a better performing card, you should go with a 256-bit GPU.

Does GPU bit matter?

Yes, the GPU bitrate does matter. A higher bitrate GPU can transfer data to and from the VRAM at a higher rate, which can result in better performance. Additionally, a higher bitrate GPU usually has more memory than a lower bitrate GPU.
