AMD V Series V120 is a single-core microprocessor for low budget notebooks. This processor, along with a large number of Athlon II, Turion II and Phenom II models, was a part of initial launch of Danube mainstream platform in May 2010.
AMD V120 processor is based on enhanced K10 microarchitecture, and is manufactured on 45nm technology. This part has one 2.2 GHz CPU core with 128 KB level 1 and 512 KB level 2 caches. To communicate with external system components the CPU utilizes two separate interfaces:
- Accesses to on-board memory are performed via integrated memory controller, that supports DDR3 memory with 1066 MHz data rate (DDR3-1066).
- To talk to on-board peripheral devices the CPU uses one HyperTransport link, clocked at 1.6 GHz.
Two separate interfaces have overall higher bandwidth, than single Front-Side Bus interface on older processor architectures, which ultimately results in higher system performance. The V Series V120 supports all common K10 features, such as new long mode with 64-bit instructions, Enhanced Virus protection feature, and Virtualization technology. The CPU incorporates MMX and 3DNow! technologies, and streaming SIMD extensions from SSE and up to SSE3 and SSE4a. Unfortunately, the V120 uses 64-bit wide SSE execution unit, therefore to process 128-bit SSE instructions the microprocessor breaks them into two 64-bit instructions, and executes each one separately, which lowers overall SSE performance. To reduce power consumption, AMD V120 processor employs a few low-power states and a PowerNow! technology. These features, together with not very high clock frequency and low core voltage, allow the CPU to fit into 25 Watt thermal envelope. V-Series V120 microprocessor is packaged into lidless (without integrated heatsink) micro-PGA package, fully compatible with S1g4 version of the socket S1. Please note, that the processor will fit into other versions of the same socket - S1g1, S1g2 and S1g3, but it's not electrically compatible with them.
In most applications, AMD V120 is the slowest, or close
to being the slowest upgradeable microprocessor from Danube platform.
Good news is that the V120 can be upgraded to more powerful dual-,
triple- and quad-core models on most laptops. Athlon II line of
processors, while offering about the same per-core performance, can be
considered a cheap upgrade due to an extra CPU core and noticeably
better performance in multi-threaded applications. Upgrade to more
expensive Turion II line of processors is worth it due to extra
performance boost in comparison to Athlon II models. Phenom II
CPUs, while been even more expensive than the Turion IIs, are recommended
if you need maximum performance in single- and dual-threaded
applications. Finally, triple- and quad-core Phenom IIs are the best
upgrade options for multi-threaded applications, and/or systems
running many processes. Be aware, though, that performance of single-
and dual-threaded tasks on these CPUs will be lower than on Turion
II/Phenom II models.
