General home users are required to install 1080P resolution can play mainstream games, using the latest RDNA2 architecture OF AMD Radeon RX 6400 is undoubtedly specifications and prices are very close to the people of the popular dessert. Intel first launched the positioning of thousands of yuan market A380 graphics card, the actual purchase value? 

The Radeon RX 6400 architecture beats the advanced energy efficiency ratio of the same 6nm process

Lets start with the specs. While the A380 and Radeon RX 6400 architectures are different, performance cant be judged by simply comparing the number of units, there are some common specifications that can make a difference. The Radeon RX 6400 uses the more efficient RDNA2 architecture. As you can see, the typical power of the Radeon RX 6400 is only 53W, less than the PCIe slot power limit of 75W, so there is no need for external power supply. The power requirements can be said to be very gentle. Also easy to make ITX cards. And A380 in the highest acceleration frequency and Radeon RX 6400 similar case, the typical whole board power reached 92W, almost 74% higher than Radeon RX 6400, energy efficiency ratio can be said to be a complete failure. The Radeon RX 6400 has 50% more light tracking units than the A380, although both cards offer hardware light tracking. For video memory, while the A380s video memory and bit width seem to have some advantages, dont forget that the Radeon RX 6400 has a very high bandwidth 16MB unlimited cache, which provides much higher efficiency when playing games. In addition to the hardware specification gap, we can not ignore the driver side of the dark technology, AMD Software Adrenalin Editions RSR (Super resolution), Radeon Anti-lag (anti-lag), AMD Link and dozens of other features are familiar and often used, which Intel alone does not offer. Finally, in game optimization, AMD has an order of magnitude advantage. After all, AMD and game manufacturers have worked together for so many years, and even dominate the game console market, which is a giant presence for a newcomer like Intel.

Overall, although for Intel such "graphics card industry newcomer" speaking, the A380 debut score is still acceptable, but in the graphics card industry and AMD for many years to compare, or appears very young. Of course, the specification comparison is only theoretical analysis, lets look at the actual situation comparison.

The Radeon RX 6400 is better

The test platform

Processor: Intel Core I9 12900K

Mainboard: Asus ROG MAXIMUS Z690 HERO EVA

Memory: Kingston FURY DDR5 6000 16GB x 2

Graphics card: AMD Radeon RX 6400

Intel ARC A380

Hard disk: WD_BLACK SN850 1TB

Power supply: Asus ROG Thor 1200W

Operating system: Windows 11 Professional

To facilitate comparison, we choose the test platform used in the first test of A380 and open Resizable Bar and Above 4G Decoding. Of course, in order to make full use of the advantages of 3A platform, we still recommend that you choose the Radeon RX 6400 platform when installing, so as to achieve the best compatibility and collaboration efficiency. First of all, the 3D Mark benchmark performance test. In the previous test of A380, we have said that the TARGETED optimization of 3D Mark on A380 is quite in place, and basically gives full play to its performance, so the score performance is ok, and the Radeon RX 6400 has a mixed performance. However, the 3D Mark score is only a reference to the level of hardware specification, and the actual game is likely to be a very different story.

When it comes to the actual game comparison, the true performance level of the A380 is exposed. The Radeon RX 6400 won nine of the ten major games tested, with CS:GOs frame-rate advantage reaching 105%, more than twice as fast! Other titles such as shadow of the tomb raider, world of warcraft: shadow nation, final fantasy xiv, DOTA2, PUBG also have a 10 to 20 percent advantage, with only a few demanding titles having relatively small differences. All told, the Radeon RX 6400 has a 19% frame-rate advantage over the A380, which is almost two levels better than AMDs advantage in game optimization.

In general, we can see that the difference between 3D Mark running score and actual game can be very large. Even if A380 can play 3D Mark and Radeon RX 6400 back and forth, it will immediately reveal its real level when it comes to actual game. In CS:GO, DOTA2, world of warcraft: The Radeon RX 6400 is far behind popular online games like Shadow Nation. So if youre building a $4,000 home console, the Radeon RX 6400 is clearly the better choice for a $1,000 card, given the smoothness and compatibility of the games and the richness of the driver features.

Bottom line: Radeon RX 6400 is the best graphics card for mainstream home devices

Now for a quick summary of the comparison. First of all, in terms of actual game performance, the average frame rate of AMD Radeon RX 6400 is about 19% higher than that of Intel ARC A380, almost two grades higher, which shows that in terms of game optimization, the gap between Intel graphics card and AMD graphics card is still very large; Secondly, in terms of energy efficiency ratio, although the same 6nm process, the typical power of Intel ARC A380 whole board reaches about 92W and requires external auxiliary power supply, while the Radeon RX 6400 is only 53W and does not need external power supply. More suitable for small cases (many Radeon RX 6400 are made into LP semi-high card) and silent users, but also lower power requirements; Again, in the driver and black technology part, although Intel also known as XeSS such screen stretching technology to improve the frame rate, but currently only in the game DEMO experience, the official version of the game will be installed after one after another, and AMD FSR games have 110+, FSR 2.0 games have 22 completely different scale. Finally is the way of sales, AMD Radeon RX 6400 is naturally open retail, full high card and half high card, players have a wide choice, and Intel ARC A380 graphics card is only through the purchase of the whole machine to obtain, players have very little choice.

We chose a representative Intel ARC A380 machine, the core configuration of this configuration is Intel Core I5 12400 + Intel ARC A380, the storage is 16GB+512GB combination, the price of the machine came to 4999 yuan, Difference one yuan cannot be called 4000 yuan configuration. By comparison, the same configuration with ZEN3 architecture AMD Rayon 5 5600 processor and Radeon RX 6400 graphics card costs only 4109 yuan, and the graphics card performance is 19% higher, the hard disk capacity is twice as high, and the power rating is 100W higher. Both the actual game experience and the future upgrade space are better. Obviously cost-effective to achieve a complete victory.

All in all, the Radeon RX 6400 is undoubtedly the best solution for the current mainstream home PCS with 1000 graphics cards, both in terms of hard power and real purchase value.
