NVIDIA chính thức giới thiệu card màn hình GeForce GTX 950

Card màn hình NVIDIA GeForce GTX 950 dựa trên kiến trúc Maxwell có 768 nhân CUDA và 2 GB bộ nhớ GDDr5 với giao tiếp 128 bit. Nó xuất hiện nhằm thay thế vị trí của GTX 750 Ti theo chúng tôi dự tính nhưng theo NVIDIA thì lại đem nó ra so sánh với GTX 650. Về kiến trúc thì GTX 950 khá giống với GTX 960 khi sử dụng GPU Maxwell GM206 với 6 Streaming Multiprocessors. Tuy nhiên, trong 1 bản báo cáo nào đó thì chúng tôi phát hiện ra sự tồn tại của 1 GPU GM206 với 7 Streaming Multiprocessors và thật không quá khó khăn thi nói rằng đó chính là GTX 950 Ti.

So sánh hiệu năng với GTX 650

Phần thú vị nhất và đáng quan tâm chính là lượng điện năng tiêu thụ của nó. Theo NVIDIA, GeForce GTX 950 sẽ yêu cầu sử dụng thêm 1 đầu nguồn PCi-e 6pin đồng nghĩa với việc TDP ~ 90W. Điều nầy tức là nó sẽ dùng điện nhiều hơn GTX 750 Ti 30W nhưng ít hơn GTX 960 30W. Lượng điện năng dồi dào đã khiến cho GTX 950 có thể dễ dàng được ép xung lên mức 1.4 GHz mà không gặp trở ngại gì trong 1 bài test nhanh.

GPU GM206-250-A1

Thiết kế tản nhiệt của GTX 950 có phần tương tự khác giống với GTX 750 Ti tức là nó sử dụng 1 fan dạng mở (không có ốp) và khác xa so với thiết kế fan lồng sóc của GTX 960. Ngõ xuất hình cũng bao gồm 5 cổng tức là 1 cổng DVI, 1 cổng HDMI và 3 cổng DisplayPort. Hi vọng trong tuần nầy NVIDIA sẽ chính thức bán card màn hình GeForce GTX 950 với mức 159$.

When the GPU is running below its limitations, it can boost to a higher clock speed in order to give increased performance.

The number of pixels that can be rendered to the screen every second.

Floating-point performance is a measurement of the raw processing power of the GPU.

The number of textured pixels that can be rendered to the screen every second.

The memory clock speed is one aspect that determines the memory bandwidth.

Shading units (or stream processors) are small processors within the graphics card that are responsible for processing different aspects of the image.

TMUs take textures and map them to the geometry of a 3D scene. More TMUs will typically mean that texture information is processed faster.

The ROPs are responsible for some of the final steps of the rendering process, writing the final pixel data to memory and carrying out other tasks such as anti-aliasing to improve the look of graphics.

Memory

The effective memory clock speed is calculated from the size and data rate of the memory. Higher clock speeds can give increased performance in games and other apps.

This is the maximum rate that data can be read from or stored into memory.

VRAM (video RAM) is the dedicated memory of a graphics card. More VRAM generally allows you to run games at higher settings, especially for things like texture resolution.

Newer versions of GDDR memory offer improvements such as higher transfer rates that give increased performance.

A wider bus width means that it can carry more data per cycle. It is an important factor of memory performance, and therefore the general performance of the graphics card.

Error-correcting code memory can detect and correct data corruption. It is used when is it essential to avoid corruption, such as scientific computing or when running a server.

Features

DirectX is used in video games, with newer versions supporting better graphics and features. The latest version is DirectX 12 Ultimate, which includes support for ray tracing, mesh shaders, and variable rate shading (VRS).

OpenGL is used in games, with newer versions supporting better graphics.

Some apps use OpenCL to apply the power of the graphics processing unit (GPU) for non-graphical computing. Newer versions introduce more functionality and better performance.

The graphics card supports multi-display technology. This allows you to configure multiple monitors in order to create a more immersive gaming experience, such as having a wider field of view.

A lower load temperature means that the card produces less heat and its cooling system performs better.

Ray tracing is an advanced light rendering technique that provides more realistic lighting, shadows, and reflections in games.

Allows you to view in 3D (if you have a 3D display and glasses).

DLSS (Deep Learning Super Sampling) is an upscaling technology powered by AI. It allows the graphics card to render games at a lower resolution and upscale them to a higher resolution with near-native visual quality and increased performance. DLSS is only available on select games.

AMD SAM / Intel Resizable BAR

Allows you to connect to a display using mini-DisplayPort.

General info

The thermal design power (TDP) is the maximum amount of power the cooling system needs to dissipate. A lower TDP typically means that it consumes less power.

A higher transistor count generally indicates a newer, more powerful processor.

Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance.

Peripheral Component Interconnect Express (PCIe) is a high-speed interface standard for connecting components, such as graphics cards and SSDs, to a motherboard. Newer versions can support more bandwidth and deliver better performance.

When covered under the manufacturer’s warranty it is possible to get a replacement in the case of a malfunction. Note: This may vary by region.

The graphics card uses a combination of water and air to reduce the temperature of the card. This allows it to be overclocked more, increasing performance.
