NVIDIA Quadro M520 vs NVIDIA Quadro M620

NVIDIA Quadro M520

► remove

Die NVIDIA Quadro M520 ist eine DirectX-12 (FL 11_0) und OpenGL-4.5 fähige Einstiegs-Workstation-Grafikkarte für Notebooks. Sie basiert wie die Consumer GeForce GTX 940MX auf den GM108-Chip der Maxwell-Serie und wird in 28nm bei TSMC hergestellt. Wie auch einige Varianten der 940MX, bietet die M520 GDDR5 Grafikspeicher und sollte daher etwas schneller sein als die alte Quadro M500M mit DDR3, die sonst jedoch auf den selben Chip basiert.

Die Quadro-Grafikkarten bieten zertifizierte Treiber, welche auf Stabiltität und Performance bei professionellen Anwendungen (CAD-, DCC-, Medizin-, Prospektions-, Visualisierungsanwendungen) optimiert sind. Dadurch ist die Performance im Vergleich zu den Consumergrafikkarten mit gleichem Chip in diesen Bereichen deutlich besser.

Leistung

Derzeit sind noch keine genauen Taktraten bekannt, jedoch sollte sich die Quadro M520 durch GDDR5 Grafikspeicher etwas schneller als die alte Quadro M500M sein.

Die Rechenkerne der Grafikkarte können per CUDA und OpenCL 1.2 auch für generelle Berechnungen herangezogen werden.

Leistungsaufnahme

Die Leistungsaufnahme der Quadro M520 liegt bei 25 Watt TGP (Max Power Consumption) und dadurch etwas unterhalb der M500M die mit 30 Watt angegeben wurde. Dadurch ist die Karte auch für dünne und leichte Notebooks geeignet.

Die NVIDIA Quadro M620 ist eine DirectX-12 (FL 11_0) und OpenGL-4.5 fähige Einstiegs-Workstation-Grafikkarte für Notebooks. Sie basiert wie die Consumer GeForce GTX 950M auf den GM107-Chip der Maxwell-Serie und wird in 28nm bei TSMC hergestellt. Sie ist die Nachfolgekarte der Quadro M600M und ähnelt der Quadro M1000M, jedoch mit weniger Grafikspeicher.

Die Quadro-Grafikkarten bieten zertifizierte Treiber, welche auf Stabiltität und Performance bei professionellen Anwendungen (CAD-, DCC-, Medizin-, Prospektions-, Visualisierungsanwendungen) optimiert sind. Dadurch ist die Performance im Vergleich zu den Consumergrafikkarten mit gleichem Chip in diesen Bereichen deutlich besser.

Leistung

Derzeit sind noch keine genauen Taktraten bekannt, jedoch sollte sich die Quadro M620 etwa unterhalb der älteren Quadro M1000M einordnen, die ebenfalls 512 Shader besitzt und einen 128 Bit Speicherbus. Die Taktraten der M620 könnten jedoch niedriger ausfallen.

In ersten SPECviewperf 12 Benchmarks ist die M1000M im Durchschnitt 9 % schneller als die neue M620.

Die Rechenkerne der Grafikkarte können per CUDA und OpenCL 1.2 auch für generelle Berechnungen herangezogen werden.

Leistungsaufnahme

Die Leistungsaufnahme der Quadro M620 entspricht laut Nvidia der alten Quadro K620M und liegt bei 30 Watt TGP (Max Power Consumption) bzw 21,2 Watt TDP. Dadurch ist die Karte auch für dünne und leichte Notebooks geeignet.
