NVIDIA GeForce GTX 485M vs NVIDIA GeForce GTX 480M SLI

NVIDIA GeForce GTX 485M

► remove

The Nvidia GeForce GTX 485M is the fastest graphics card for laptops at the time of announcement (Q1 2011). It is based on the GF104 chip and offers all 384 shader cores and the full 256 Bit memory bus. Due to the high clock rate of 575 MHz, it is significantly faster than the old GeForce GTX 480M of which it replaces. It also supports DirectX 11 and OpenGL 4.0.

Other than the GeForce GTX 480M, the 485M is no longer based on a trimmed down GF100 chip, but on the related GF104 instead. The GF104 is designed for the consumer sector and has a total of 384 cores. A number of cores may be disabled, for example the 470M with only 288 active cores.

The technology of the GF104 differs quite a bit from the GF100 chip (which was actually designed for professional use). The GF104 has more shaders (3x16 vs. 2x16), texture units (8 vs. 4) and SFUs (Special-Funciton-Units) per Streaming-Multiprocessors (SM). Nvidia now uses the superscalar architecture as there are still only two warp schedulers supporting three shader blocks. In theory, this helps to utilize the shaders more efficiently and increases the performance per core.

However, in the worst case, the performance can drop below the GF100 architecture (and its predecessors). The ECC memory protection, important in professional applications, was completely omitted and the FP64 was trimmed down (only 1/3 of the shaders are FP64-capable, only 1/12 of the FP32 performance). Because of these reductions in the GF104, the size of a SM increased only by 25% despite the higher number of shaders.

Note that it is not possible to directly compare the number of cores to the AMD Radeon graphics cards (e.g. HD 5870) or even to Nvidia's own predecessors (e.g., G92b), because shader architecture and clock rates are significantly different in the GF104 chip.

Performance

In our extensive test of the GeForce GTX 485M, we found that the GTX485M is significantly faster than the old GeForce GTX 480M (at the same TDP rating). The performance is on a level with two GeForce GTX 460M in SLI mode. Nearly all games are therefore playable in highest details and resolutions. Even demanding games like Mafia 2 or Battlefield Bad Company 2 can run fluently in 1080p with maximus detail settings. Detailed benchmarks can be found at the end of this page.

Features

What's new compared to the GF100 is support for Bitstream transfer of HD Audio (Blu-Ray) via HDMI in the GF104 chips. Similar to the HD 5850, the GTX 485M can transmit Dolby True HD and DTS-HD via Bitstream to compatible receivers without quality loss.

For decoding HD videos, the GTX485M supports PureVideo HD. The built-in Processor 4 (VP4) handles Feature Set C. As a result, MPEG-1, MPEG-2, MPEG-4 Part 2 (MPEG-4 ASP - z.B. DivX or Xvid), VC-1/WMV9 and H.264 can be fully decoded by the graphics card (VLD, IDCT, Motion Compensation, and Deblocking). Furthermore, two streams can be simultaneously decoded in realtime, e.g. Blu-Ray Picture-in-Picture (2x1080p lt DXVAChecker). In addition, PureVideo HD indicates HDCP encoding for digital interfaces.

The shader cores (also called CUDA cores) can also be used for general computations (e.g. Video Transcoding) by using the interfaces CUDA, DirectCompute 2.1 or OpenCL. Thanks to PhysX, the 485M can also perform physics calculations.

According to Nvidia, the support for 3D Vision includes support for the recent HDMI 1.4a standard as well. If enabled by the laptop manufacturer, content such as 3D games, 3D web streaming videos, 3D pictures and 3D Blu-Ray videos can be displayed on a 3D-capable TV (via discrete 3DTV Play) or on the internal notebook 3D display.

With regards to energy demand, the GTX 485M should be on par with the GeForce GTX 480M. In other words, both graphics cards should draw about 100 Watts each when including their respective memory and MXM boards. Due to the higher performance from the 485M, the performance/power efficiency here has clearly been improved.

Compared to desktop graphics cards, the performance of the 485M should be on par with a GeForce GTX 460 768MB which features less cores but operates on higher clock rates.

NVIDIA GeForce GTX 480M SLI

► remove NVIDIA GeForce GTX 480M SLI

The NVIDIA GeForce GTX 480M SLI is a high-end graphics solution for laptops based on two GTX 480M graphics cards in SLI mode. Each card usually renders a single frame in an alternating manner. Therefore, it may suffer from micro stuttering in low fps ranges of 30fps. This happens because of different timespans between two frames (e.g. Irregular delays between sequential frames).

The GeForce GTX480M SLI supports the same features as a single GTX 480M card. A single card is based on the Fermi architecture. Therefore, it supports DirectX 11 and is produced in 40nm at TSMC. Featuring 352 cores, the GTX480M is similar to the desktop GTX 465 but features a lower clock rate. The GeForce GTX 480M is combined with 2 GB of fast GDDR5 graphics memory (dedicated) and the overall performance should be superior to the Mobility Radeon HD 5870.

The GF100 aka. Fermi chip was redesigned from scratch and features 3 billion transistors (with all 512 shaders). Compared to the desktop Radeon HD 5870 with 2.13 billion transistors or the Mobility Radeon HD 5870 (RV870) with 1.04 billion transistors, the GTX480M chipset is quite large.

The mobile Fermi chip is stripped down to 352 shader cores (1-dimensional) with 32 ROPs and 44 Texture Units. The memory bus is 256 bit wide, but due to the fast GDDR5 memory, this should not be a bottleneck. The power consumption is specified with 100 Watt TDP including the MXM board and the 2 GB GDDR5. AMD usually specifies the TDP of the chip alone, therefore this value is not directly comparable. Still, the GTX 480M is only suited for very large DTR laptops with a good cooling system. Originally, only Clevo sold 17" (D901F) and 18" (X8100) barebone systems.

The fast performance of the Nvidia GeForce GTX 480M SLI is marginally better than two ATI Mobility Radeon HD 5870 in Crossfire Mode (CF), partly because of the superior driver support from Nvidia.  This means the GTX 480M SLI was the fastest graphics solution for laptops at the time of arrival (2010-06). It allows the user to play all current games in high resolutions and detail settings with Antialiasing activated. Only Metro 2033 and Crysis have to run at lower settings (see below).

Still, in some games the performance gain from SLI may be very small or sometimes a single card may be even a bit faster (due to no SLI support and overhead). You can still disable SLI through the drivers in this case. In our gaming tests, a single 480M was about 16% (Starcraft 2) to 48% (Far Cry 2) slower than the SLI combination. Otherwise, most modern games run about 40% slower on the single card compared to the SLI setup. (see expandable gaming charts below). Due to the fast tessellation unit, upcoming DirectX 11 games may have an advantage over the AMD 5000 series.

Similar to the GeForce 300M series, the GeForce GTX 480M supports PureVideo HD with VideoProcessor 4 (VP4 with Feature Set C). As a result, the GPU is able to fully decode HD videos in H.254, VC-1, MPEG-2, and MPEG-4 ASP. By using Flash 10.1 or later, the graphics card can also accelerate Flash videos, thus taking workload off of the CPU.

The rendering cores of the Nvidia GeForce GTX 480M can be used for general calculations by means of CUDA or DirectCompute. E.g., the encoding for HD videos can be done significantly faster by using the shader cores of the GPUs rather than using most modern CPUs. PhysX is also supported by the mobile Fermi to calculate physics effects in supported games. Furthermore, a single GTX480M can be used to calculate PhysX while the other card renders the game.

Compared to desktop GPUs, the Geforce GTX 480M is comparable to an underclocked Nvidia GeForce GTX 465 SLI combination (607/1200 clock speed).
