The GeForce RTX 4070 Laptop is only 15% faster vs. RTX 3070
Thanks to the manufacturer of portable equipment Mechrevo (via IThome), we can already know the performance improvements of both the GeForce RTX 4070 Laptop like her little sister GeForce RTX 4060 Laptop. Specifically, we are talking about graphics chips for laptops and, in both cases, they were compared with their previous generation counterparts. These are the GeForce RTX 3070 and RTX 3060.
To make matters worse, the performance tests are tied to the benchmarking software. 3DMark. This is the closest benchmark when it comes to representing the final performance of these GPUs in the gaming section. We must remember that these graphs will arrive next February 22 together to the GeForce RTX 4050. With them, the family is complete, since the RTX 4090 and RTX 4080 debuted a few weeks ago.
GeForce RTX 4070 Laptop vs GeForce RTX 3070 Laptop in 3DMark
According to the company, in the 3DMark Fire Strike benchmark, the GeForce RTX 4070 Laptop is barely 11% faster than its predecessor. In a more demanding benchmark such as 3DMark Time Spy, we are talking about being 15% faster.
In this way, the difference in performance will not really compensate the extra cost that the laptop may have. And more taking into account that all this will be linked to a CPU that is also more powerful, contributing to its performance improvement. And of course, another additional cost.
For context, this small performance difference is due to the RTX 4070 using 4,608 CUDA Cores Ada Lovelace. These are joined by 8 GB of 16 Gbps GDDR6 memory and a 128 bit. Its predecessor, the RTX 3070, boasts of offering a higher, albeit older, core count. Specific, 5,120 CUDA Cores Ampere at 8nm Samsung (vs 4nm TSMC). In addition, it has an advantage, its memory interface of 256 bit makes you have a higher bandwidth than 448GB/s (vs 256GB/s)
GeForce RTX 4060 Laptop vs GeForce RTX 3060 Laptop in 3DMark
Exactly the same thing happens with this GPU, although luckily, at least there is a more comfortable difference in performance. In 3DMark Fire Strike is performance difference is 30%while in 3DMark Time Spy drops slightly to offer 25% more performance.
In this case, the GeForce RTX 4060 Laptop offers 3,072 CUDA Cores with the same memory configuration as its older sister. This also implies the same bandwidth of 256GB/s. Its predecessor also offers a higher number of cores: 3,840 CUDA Cores. To this is added that it also offers a greater bandwidth that reaches 336 GB/s.
As in the desktop market, it is felt that the lower-middle range it is more medium-low than ever. In essence, the GeForce RTX 4070 Laptop specs would fit the bill. as an RTX 4060 Laptopand more with that very poor 128-bit memory interface.
Obviously it would be interesting to see the performance of the RTX 3060 Ti and RTX 3070 Ti vs the GeForce RTX 4060 and RTX 4070, since the difference in performance will be minimal and all of it costing much less money. Remember, novelty is paid for, but in many cases, it is not worth paying for it.
