RX 6400 vs GTX 1650: Compare AMD and Nvidia Graphics Cards | plates

RX 6400 and GTX 1650 are graphics cards from AMD and Nvidia. Both promise good value for money for those looking to save money on a new GPU. Available in Brazilian online retail at prices starting at R$999, the cards offer at least 4GB of memory and promise good performance for games in Full HD resolution.

So, two models that can be strategic options for beginner gaming computers or even for those that do not require so much performance. Further, TechTudo details and compares GPU specs to help you decide which AMD or Nvidia card is worth investing in.

The AMD card is a more modern model, released in 2022, which is why it offers some specifications that are significantly ahead of the Nvidia model. The RX 6400 has a boost clock of up to 2321 MHz, while the Nvidia GPU offers up to 1590 MHz. This is a difference that can make a big difference when the cards are very demanding, challenging the GPU’s frame rate.

The GTX 1650 appears in versions with 4 GB of VRAM in GDDR5 or GDDR6 standards, but always with a 128-bit interface. Meanwhile, the RX 6400 offers the same 4 GB in modules with GDDR6 technology and 128-bit bandwidth. Without a doubt, the best scenario is in 4 GB GDDR6, after all, it is a technology that offers more performance than the GDDR5 present in some versions of the GTX 1650.

Both cards have basically the same connectivity options. However, as the GTX 1650 was released before, the card still has models that bring DVI connection, which is not so used today, but is very present on slightly older monitors.

According to data from specialized benchmark sites, even as an older card, the GTX 1650 can offer performance that can outperform the RX 6400 by up to 12% in some scenarios. The performance can be justified by the higher bandwidth, even with versions that have GDDR5 memory modules.

Despite the difference, according to the tests, in most graphics applications the performance of the cards is well balanced. Overall, the GTX 1650 just has a more stable average frame rate.

AMD and Nvidia GPUs do not consume very much, which can be interesting for those who intend to install the card in simpler systems. However, since it is a more modern design, the tendency is for the AMD card to be more efficient, so users who opt for the model have a small energy saving compared to GTX 1650 users.

According to AMD, the RX 6400 has a consumption of around 53 W, while the recommended power supply to use the card needs at least 350 W. On the other hand, the GTX 1650 is a card with a consumption of 75 W, so Nvidia recommends using it with a power supply of at least 300 W. The GTX 1650 also requires a complementary six-pin power connector, so some users using simpler power supplies may need to invest in a new PSU.

With a slightly simpler architecture, the Nvidia card basically supports the latest APIs and supports Nvidia G-Sync. This is a feature that optimizes frame playback on compatible monitors and displays to prevent image tearing known as tearing.

In addition to promising good performance and supporting basically the same features as the GTX 1650, the RX 6400 has the distinction of supporting technologies such as Ray Tracing and FSR, which improve lighting in games and compatible software. In addition, they automatically optimize performance by performing some kind of image upscaling, in something similar to Nvidia’s DLSS, which in turn is not present in the GTX 1650.

Both cards can be found with some ease in Brazilian online retailers. In terms of price, the AMD card has a certain advantage. Some versions of the RX 6400 are appearing in online retail at prices starting at R$999, which is a very interesting price considering that this is a recently launched card.

The Nvidia card, on the other hand, is very attractive in the market, which makes it always in high demand, considering its ability to provide good performance even after some time after its release. Currently, the GTX 1650 appears for values ​​of R$ 1235 for the version with GDDR6 memory.

Given that the difference in performance between the cards isn’t huge, it’s safe to say that the experience with both cards shouldn’t be that different. For those who want to save money and want a more modern card with Ray Tracing support, the right choice is the RX 6400, which nevertheless promises to be a more energy efficient card.

For those who prioritize performance, the GTX 1650 is worth looking at, which, while an older card, still serves those looking for an entry-level gaming GPU very well.
