The new company focused on the mobile graphics market, and became a major player in this space. The company was purchased by HTC in Although primarily a mobile technology company, they still produce graphics accelerators for home computers under the "S3 Chrome" brand name. This was the last series available on AGP cards. Products are based on a slightly repolished Tesla microarchitecture, adding PCIe 2. The Master card shipped with a proprietary DVI Y-dongle, which plugged into the primary DVI ports on S3 Graphics GammaChrome cards, and into the monitor cable and this dongle serves as the main link between both cards, sending incomplete images between them, and complete images to the S3 Graphics GammaChrome.

The slave graphics card needed to be from the family as the master. This is similar to X CrossFire, which also uses PCI Express, except that S3 Graphics GammaChrome Xpress had been built for low-latency and high-speed communication between graphics cards. ATI has said that revisions of the Catalyst driver suite will contain what is required for X dongleless CrossFire 6. S3 Graphics GammaChrome

SLI is an algorithm of parallel processing for computer graphics, meant to increase the power available for graphics. SLI allows two, three, or four graphics processing units to share the workload when rendering real-time 3D computer graphics, ideally, identical GPUs are installed on the motherboard that contains enough PCI-Express slots, set up in a master-slave configuration. All graphics cards are given an equal workload to render, an example, in a two graphics card setup, the master works on the top half of the scene, the slave the bottom half. Once the slave is done, it sends its render to the master to combine into one image before sending it to the monitor, the SLI bridge is used to S3 Graphics GammaChrome bandwidth constraints and send data between both graphics cards directly.

Since these graphics cards do not use as much bandwidth, data can be relayed through just the chipsets on the motherboard.

However, if there are two graphics cards installed and the SLI bridge is omitted, the performance will suffer severely as the chipset does not have enough bandwidth. Configurations currently include, 2-Way, 3-Way, and 4-Way SLI, uses two, three, or four individual graphics cards S3 Graphics GammaChrome.

To do this, the frame is split horizontally in varying ratios depending on geometry, for example, in a scene where the top half of the frame is mostly empty sky, the dividing line will lower, balancing geometry workload between the two GPUs. For example, in a Two-Way setup, one GPU renders the odd frames, S3 Graphics GammaChrome outputs are sent to the master for display 7.

In contrast, PCI Express is based on point-to-point topology, with separate serial links connecting every device S3 Graphics GammaChrome the root complex. Due to its bus topology, access to the older PCI bus is arbitrated. Furthermore, the older PCI clocking scheme limits the bus clock to the slowest peripheral on the bus, in contrast, a PCI Express bus link supports full-duplex communication between any two endpoints, with no inherent limitation on concurrent access across multiple endpoints.


In terms of bus protocol, PCI Express communication is encapsulated in packets, the work S3 Graphics GammaChrome packetizing and de-packetizing data and status-message traffic is handled by the transaction layer of the PCI Express port. Radical differences in electrical signaling and bus protocol require the use of a different mechanical form factor and expansion connectors, PCI slots, the PCI Express link between two devices can consist of anywhere from one to 32 lanes. In a multi-lane link, the data is striped across lanes.


The lane count is automatically negotiated during device initialization, and can S3 Graphics GammaChrome restricted by either endpoint, for example, a single-lane PCI Express card can be inserted into a multi-lane slot, and the initialization cycle auto-negotiates the highest mutually supported lane count. A link is a point-to-point communication channel between two PCI Express ports allowing both of them to send and receive ordinary PCI requests and interrupts, at the physical level, a link is composed of one or more lanes. Low-speed peripherals use a link, while a S3 Graphics GammaChrome adapter typically uses a much wider and faster lane link. A lane is composed of two differential signaling pairs, with one pair for receiving data and the other for transmitting, thus, each lane is composed of four wires or signal traces.

Conceptually, each lane is used as a byte stream. Physical PCI Express links may contain one to 32 lanes. The VIA Nano was released by VIA Technologies in after five years of development by its CPU division and this new Isaiah bit architecture was designed from scratch, unveiled on 24 Januaryand launched on May 29, including low-voltage variants and the Nano brand name.

In this case, the codename CN was used in the United States by Centaur Technology, biblical names are used as codes by VIA in Taiwan, and Isaiah was the choice S3 Graphics GammaChrome this particular processor and architecture. Several independent tests showed that the VIA Nano performs better than the single-core Intel Atom across a variety of workloads, the benchmark software used had been released before the release S3 Graphics GammaChrome VIA Nano.


Benchmarks run by VIA claim that a 1. Instructions fusion, Allows the processor to combine some instructions as an instruction, reducing power requirements. Improved branch prediction, Uses eight predictors in two pipeline stages, CPU cache design, An exclusive cache design means that contents of the L1 cache is not duplicated in the L2 cache, providing a larger total cache. Data prefetch, Incorporating new mechanisms for data-prefetch, including both the loading of a special line cache before S3 Graphics GammaChrome the L2 cache and a load to the L1 cache.

MEDIA-A executes floating-point add instructions, integer SIMD, encryption, divide, because of the S3 Graphics GammaChrome introduced with the 2 Media units, Media computation can provide four add and four multiply instructions per clock. A new implementation of FP-addition with the lowest clock-latency for a x86 processor so far, almost all integer SIMD instructions execute in one clock 9. Compared to single data rate SDRAM, the S3 Graphics GammaChrome SDRAM interface makes higher transfer rates possible by more strict control of the timing of the electrical data, implementations often have to use schemes such as phase-locked loops and self-calibration to reach the required timing accuracy.
