Jedoch dürfen die Operationen nicht voneinander abhängig sein.
Die 5-dimensionalen Shader-Einheiten können sich theoretisch im Verhältnis 1:1:1:1:1 aufsplitten und verhalten sich dann theoretisch wie die Skalarshader von Nvidia. Diese übernehmen je nach Anforderung die Aufgaben der Shader und Pixelpipelines. MSI hat auf der CES bereits das Bravo EX6 und "normalen" DDR3 als Grafikspeicher angekündigt.ĭie HD 4650 basiert auf den RV730 Chip und bietet 320 Stream-Prozessoren (64 5-dimensionale Shader Einheiten). 1024 MB DDR3 zum Preis von 512 MB GDDR3 auf der Karte verbauen (mit Marketing-Vorteil).
Dieser ist mit einem 16 Bit Bus zwar langsamer als der GDDR Speicher mit der 32 Bit Verbindung, jedoch im Einkauf auch deutlich billiger. mit Turion X2) erreicht die 4650 jedoch deutlich niedrigere Leistungsdaten (nur etwa 5000 Punkte im 3DMark 06).Įine Besonderheit der Mobility HD 4000 Serie ist die Möglichkeit neben GDDR (Grafics-DDR) auch normalen DDR Hauptspeicher zu verwenden. Mit langsamen DDR2 Speicher und langsamen Prozessor gepaart (z.B. Dank der hohen Anzahl an Shadereinheiten, zeigt die Karte jedoch trotz des 128 Bit Speicherbus eine gute Performance (ohne AA). Die Taktrate des Grafikchips kann von 450 - 550 MHz reichen (Speichertakt 600 - 800 MHz). Ältere (DirectX 9) Spiele sollten jedoch auch in hohen Details flüssig laufen (siehe Spieleliste weiter unten). Highend Spiele wie Crysis laufen nur in mittleren Details bei geringen Auflösungen flüssig. Die 4650 war die Vorgänger-Generation der Mobility Radeon HD 5650, welche mehr Leistung und DirectX11 Shader bietet.ĭurch die deutlich geringeren Taktraten der 4650 im Vergleich zur 4670 ist die Spieleleitung etwas geringer. I'm pretty good at that (they really need a graph which shows every CPU for up to 5 years and the latest graphic card from each AMD and NVidia which "balance" this older system.ATI Mobility Radeon HD 4650 ► remove from comparisonĭie ATI Mobility Radeon HD 4650 von AMD ist eine DirectX 10.1 fähige Mittelklasse Grafikkarte für Notebooks.
It takes some experience to estimate what graphics card is best to take full potential of a computer, especially if it's older. A perfectly "balanced" system is one in which 50% of a persons games are limited by his CPU and 50% are limited (bottlenecked) by his graphics card. More than $50 tends to be overkill unless you have a quad-core CPU and overclock to more than 4GHz.ĩ) *Gaming performance is usually limited by the CPU or by the graphics card. Measure your case and motherboard and compare to the HSF to ensure no issues (hitting a motherboard heatsink or RAM). Even a $20 HSF significantly reduces noise both in use and in idle mode. It is both organized very well and also quite competitive for most parts.Ĩ) Many CPU's can easily gain 15% to 25% increases if a good after-market Heatsink/Fan is installed. For a high-end graphics card like the GTX560Ti, a 750W Corsair is a good example of a compatible PSU.ħ) NCIX is the best online store to compare parts. I would add to this that, if you ever want a Gaming graphics card, you need to also know what CPU you are using as the CPU might be a bottleneck.ġ) your current cards are just fine if you are a non-gamerĢ) web site are being optimized for DX11 cards but most web sites will take at least a year, maybe two to rewrite their codeģ) Most video games approach maximum quality settings with a GTX560Ti which costs about $220 roughly, provided the CPU is not a bottleneck.Ĥ) On the other hand, a $100 video card provides a much poorer gaming experience for modern games, on average.ĥ) Any graphics card will fit in any motherboard with a PCI-express 8x or 16x slot.Ħ) You need to examine the Wattage, Amperage (+12V rail), and connections of your Power Supply. Here's something else to read about Power Supplies. You need a DX11 card to watch the Internet Explorer 9 demos. Here's a cool web site from Microsoft that talks about this. In short, web pages optimized for DX11 run much smoother.
The most notable feature is most of the page, including text being loaded into the graphics cards memory and being rescaled by the graphics cards GPU.
**Neither card you mentioned is compatible with the new code being written for web pages. It will take a few years for most web sites to rewrite their code.Īnd again, the $25 card I mentioned would work great for this. New versions of Internet browsers are being re-written to take advantages of the hardware that DX11 cards offer. There are basically few programs yet besides games that make use of graphics cards. FYI, if you do not play video games, there is a new card for $25 which works identically for basic usage on the Internet and playing video as the most expensive card available.
