Although Intel Sandy Bridge and AMD Fusion APU are rushing to integrate GPUs to squeeze out low-end discrete graphics cards, the notebook video card market is still burning: After AMD released the second-generation Radeon HD 6000M series yesterday, NVIDIA launched its own today. The GeForce 500M series, but both are not very kind. The AMD Radeon HD 6000M can be divided into six sub-families, half of which are Mobility Radeon HD 5000 series specifications fine-tuned and renamed, and the other half is the real second-generation DX11 core. The NVIDIA GeForce 500M series are all products of the old core adjustment specifications. At the same time, more GeForce 400M/300M series models have been added at the high and low end, which has become more chaotic across three eras.
From the product list below, we can see that the GeForce 500M series are all used for performance and mainstream notebooks, strictly speaking, GeForce GT 500M sub-series, a total of GeForce GT 555M/550M/540M/525M/520M five models; The GeForce 400M series focuses on high-end gaming notebooks, specifically the GeForce GTX 400M. This time only one GeForce GTX 485M has been added; GeForce 410M and GeForce 315M have been added to the entry-level notebook space.
Among them, the GeForce GT 540M had already landed on the domestic market first, and Acer also introduced several notebooks that use this card, such as the Aspire 4741G and Aspire 5742G.
NVIDIA claims that Sandy Bridge and GeForce will become the best partners to bring together better desktop, mobile computing and graphics performance, and even claim that there are more than 200 such models are being designed and developed, 60 more than last year. %, the manufacturer covers Acer, Asus, Dell, Lenovo, HP, Samsung, Sony, Toshiba and other major brands.
GeForce GTX 485M will undoubtedly become the new flagship of NVIDIA notebook graphics card, based on GF104 core, with a complete 384 stream processors (comparable to the upcoming desktop GeForce GTX 560), core/stream processor frequency 575/1150MHz, with 256 -bit GDDR5 memory, equivalent frequency 3000MHz, bandwidth 96GB/s, supports dual-card SLI.
Compared to the earlier released GeForce GTX 480M, the card is downgraded from GF100 to GF104 on the core, and the number of stream processors is smaller, but the frequency of each unit is greatly increased. As a result, the computing capacity is increased by 48%, the bandwidth is increased by 25%, and the performance is improved. Should be slightly better, power consumption and temperature will be greatly reduced, and instead it will be logical.
The GeForce GT 500M series are all based on GF108 cores, and all memory uses DDR3 particles. Among them, GeForce GT 555M has the highest specification with 144 stream processors, core/stream processor frequencies of 590/1180MHz, 192-bit memory bandwidth, etc. Effective frequency 3600MHz, bandwidth 43.2GB/s, no longer supports double-card SLI, its replacement object is GeForce GT 445M naturally. From the photo point of view, the card core still needs to install a thermal protection cover.
The GeForce GT 550M/540M/525M are 96 stream processors with a core frequency of 740/672/600MHz, which in turn reduces the memory bit width to 128-bit. The equivalent frequency is 1800MHz and the bandwidth is reduced to 28.8GB. /s. They will replace the GeForce GT 435M/425M/420M, respectively. It is from here that the core power consumption and temperature are greatly reduced, and it is no longer necessary to install a thermal protection cover.
According to the test, GeForce GT 425M can win 55-96% on average in comparison with HD Graphics 3000 in low-grade and mid-range quality, but the latter can basically flatten the former when it comes to a more powerful quad-core processor such as Core i7-2820QM.
The GeForce GT 520M is also a GF108 core, but the number of stream processors is cut to half as many as 48. The core frequency is used to make up for a higher 740MHz, while the memory bandwidth is once again reduced to 64-bit, and the equivalent frequency is reduced to 1600MHz. Bandwidth 12.8GB/s. It will replace the GeForce GT 415M, but will definitely face the strong impact of Intel Sandy Bridge HD Graphics 3000.
The GeForce 410M seems to be a backwards generation, but in fact it is a GF108 core like the GeForce GT 500 series, with 48 stream processors, a core frequency of 675MHz, a floating point performance of 73GFlops, a 64-bit memory interface, and a GDDR3/DDR3 granularity. The maximum capacity of 512MB, the highest frequency of 1600MHz, the same bandwidth of 12.8GB/s, the output also fully supports VGA, SL-DVI, DL-DVI, HDMI, DisplayPort.
GeForce 315M is a true old core, entry-level GT218, supports DX10.1 instead of DX11, only 16 stream processors, core frequency 606MHz, memory configuration and GeForce 410M exactly the same. At the very least, it is a "discrete graphics card."
