Not long ago, Intel officially released the Arc Sharp series of discrete graphics cards codenamed "Alchemist" (alchemist) (see "Intel Arc Sharp Unique Display Most Complete Analysis"). Subsequently, foreign media also released the evaluation data of Samsung Galaxy Book Pro2 (i7-1260P+Arc A350M) (for details, see "Intel Iris Unique Arc A350M Running Score Exposure!"). 》）。
In the 3DMark benchmark, if the 100% score of the GeForce MX450 in the Oversized Cup (28W, GDDR6 memory) is used as the benchmark, the Arc A350M unique display is 31.8% stronger than it, surpassing the Ryzen 7 6800H integrated Radeon 680M and NVIDIA's just-released GeForce MX550 unique display.
In the actual game test, there are also foreign media to get the i7-12700H + Arc A370M exclusive display and Ryzen 5600H + GTX 1650 platform comparison data, the result is that the A370M is not an opponent at all, the performance of the A350M is definitely worse.
A few days ago, South Korean Tubing blogger BullsLab found the problem of "negative optimization" of Intel drivers.
After updating the driver, the blogger discovered that the Arc A350M could almost double the frame count of the actual game by turning off a feature called Dynamic Tuning Technology (DTT) !
DTT, one of the components of Intel Deep Link technology, is a dynamic power sharing function similar to AMD SmartShif and NVIDIA Danymic Boost, that is, dynamically adjusting the power ratio of CPU and GPU according to different loads, such as allocating more power consumption to GPUs in game scenarios.
Before turning off the DTT function, the Test Platform Galaxy Book Pro2 equipped with arc A350M unique display power consumption is between 18W and 23W, and the processor power consumption is only 14W to 16W, which is equivalent to the low frame rate caused by CPU frequency reduction.
After turning off the DTT function, the Arc A350M unique display power consumption can be increased to between 24W and 30W, and the power consumption of the processor has also increased to 23W to 28W, and the CPU and GPU can be in a full blood state, so the performance improvement is significant (but the corresponding power consumption and heat generation will also increase, as shown in the figure CPU temperature soared by 20°).
On the whole, Intel's existing drivers are still suspected of negative optimization, and it is hoped that the Arc unique thin and light book can solve the problem of driving backwards before it is officially listed in China, at least the best balance between power consumption, performance and temperature can be found.
